This document outlines SPACE as a performance framework for elite golf swings, defined by Speed, Power, Accuracy, Consistency, and Efficiency. According to Henrik Jentsch, these qualities are not achieved through effort alone, but through a specific biomechanical advantage: creating physical space between the upper and lower body during the transition and downswing.

Elite players differentiate themselves by avoiding the common amateur fault of crowding the swing path. Using insights from 3D motion capture, the text explains that professionals move the lower body slightly downward and backward in transition—often described as a subtle squat-like move. Instead of spinning the hips early toward the target, the lower body works under the torso, creating room for the arms and club to drop naturally into position.

This movement produces several critical effects. At setup, elite players establish a small buffer between the hands, shaft, and torso. During transition, the hips shift down and back rather than firing laterally. As a result, the club shallows naturally, energy transfers efficiently from the ground up, and the arms sync with the body without manipulation. This sequence generates Speed and Power, while the improved geometry of the swing delivers Accuracy and Efficiency. Most importantly, it unlocks Consistency, the defining trait of elite ball strikers.

In contrast, many amateurs spin their hips too early from the top. This pulls the upper body behind the lower body, trapping the club and forcing late compensations. The outcome is familiar: blocked shots, hooks, and unstable tempo. Without space, the arms cannot move freely or square the club naturally.

Practical drills—such as using an alignment rod to feel the hips move “back and under”—help players experience this correct transition. The key sensation is allowing the lower body to create room first, before the powerful release through impact.

In essence, SPACE is both the hardware and the software of the golf swing. When the body creates physical room, the five performance pillars—Speed, Power, Accuracy, Consistency, and Efficiency—can operate at their highest level.

This Podcast presents a technical evaluation of a golfer’s putting performance using high-speed ball-roll analysis. The focus is on how efficiently the ball transitions from impact into true roll, defined as pure forward rotation without skidding or bouncing. Objective metrics such as launch angle, spin rate, skid distance, and true roll distance are used to assess stroke efficiency and equipment suitability.

The analysis shows that although the basic stroke mechanics were solid, the ball consistently reached true roll later than optimal. This delay was primarily caused by unintentional backspin and vertical instability immediately after impact. These effects reduced predictability in distance control and increased sensitivity to green conditions.

Launch angle is identified as the most critical variable. Because a golf ball rests in a shallow depression (“nest”) created by its own weight, it requires sufficient vertical lift to exit cleanly. A launch angle below 0.75° traps the ball in this depression, increasing friction and causing an inconsistent start. Conversely, a launch angle above 2.5° sends the ball momentarily airborne, leading to bounce and delayed roll. The optimal window between 0.75° and 2.5° minimizes both friction and bounce. A measured launch angle of approximately 1.55° is considered technically sound and well within this ideal range.

Spin profile strongly influences the transition to true roll. Backspin (negative RPM) forces the ball to skid before rolling forward, extending the unstable phase after impact. This skidding increases distance variability and susceptibility to surface irregularities. Immediate forward or neutral spin shortens the skid phase and allows the ball to stabilize earlier.

Skid and bounce metrics quantify horizontal sliding and vertical instability after impact. Excessive skid prolongs the period during which the ball is affected by grain, slope, or moisture. Bounce prevents continuous surface contact and delays true roll until the ball fully settles.

True roll distance serves as a summary indicator of efficiency. True roll is achieved when the ball completes one full rotation every 5.25 inches of travel. An efficient stroke reaches this state within approximately 6–8 inches. Longer distances indicate energy loss caused by excessive loft, poor strike location, or insufficient forward spin.

Shaft angle and impact mechanics are the primary input variables controlling these outcomes. Inconsistent shaft lean alters dynamic loft, producing variable launch and spin conditions even with identical stroke speed. A stable, forward-leaning shaft position promotes consistent launch, reduces backspin, and improves repeatability.

Overall, the report emphasizes that precise measurement and data-driven adjustments are essential for optimizing putting performance, outperforming intuition-based feedback in both equipment fitting and coaching decisions.

This report examines how professional golf maintained momentum during the late 2025 season, despite the traditional year-end slowdown. Through innovative formats, breakthrough performances, and new technology-driven leagues, the sport continued to evolve and position itself for future growth.

A central highlight was the Grant Thornton Invitational, which once again confirmed the viability of mixed-gender competition at the elite level. Andrew Novak and Lauren Coughlin delivered a record-setting performance, finishing at 28-under-par (188) to win by three shots. Novak’s consistent iron play repeatedly created scoring chances, while Coughlin’s calm and precise putting under pressure converted those opportunities. Three teams tied for second place at 25-under-par, underlining the depth and competitiveness of the field. The rotating formats—scramble, foursomes, and modified four-ball—demonstrated how collaborative competition can enhance both entertainment value and fan engagement.

On the DP World Tour, Jayden Schaper produced one of the most impressive late-season runs in recent years. His breakthrough came at the Alfred Dunhill Championship in South Africa, where difficult weather shortened the event to 54 holes. Schaper remained composed, finishing at 16-under-par before defeating Shaun Norris in a playoff to claim his maiden title. He immediately followed that victory with another playoff win at the AfrAsia Bank Mauritius Open, this time beating Ryan Gerard after both players reached 22-under-par. Securing back-to-back titles via playoffs highlighted Schaper’s resilience, consistency, and ability to perform under pressure.

While several major tours were in off-season mode, the sport remained active beyond traditional competition. Scottie Scheffler was named PGA Tour Player of the Year for the fourth consecutive season, reinforcing his dominance, while the LPGA Q-Series Final Stage awarded full 2026 tour status to the top 25 finishers, spotlighting the next generation of talent.

A major innovation was the launch of TGL’s second season, a high-tech indoor league founded by Tiger Woods and Rory McIlroy. Played inside a purpose-built arena, TGL combines real ball-striking with advanced simulator technology to create a fast-paced, made-for-television product. Team-based match play, including three-on-three alternate shot and singles matches, delivers tension, speed, and entertainment, with matches often decided on the final hole. Enhanced visuals and streamlined presentation further modernize golf consumption for a new audience.

In summary, professional golf did not stand still during the late 2025 off-season. Mixed-team formats, emerging stars, and technology-driven leagues such as TGL illustrate how innovation and strategic evolution are shaping a dynamic and forward-looking future for the sport.

This podcast explores the technical mechanics of putting, focusing on how a golf ball transitions from impact to true roll. After being struck, the ball moves through four key phases:

1. Launch Phase: The ball lifts slightly off the green.

2. Skid Phase: The ball slides without full rotation.

3. Transition Phase: Sliding slows, rotation takes over.

4. True Roll: The ball rolls end-over-end without slipping.

The goal in elite putting is to minimize the skid phase and reach true roll as early as possible—ideally within 10–15 cm of impact. Once true roll begins, the ball behaves predictably, improving distance control and start line accuracy.

Launch Angle: The Critical Variable

The launch angle determines how cleanly the ball leaves the putter and escapes the “nest” (its slight depression in the grass).

• Too low (< 0.75°): The ball drags on the surface, causing grabs or bounces.

• Too high (> 2.5°): The ball goes airborne, landing inconsistently.

• Ideal range: 0.75°–2.5°

Staying within this range ensures smooth launch, shorter skid, and early true roll.

Measuring with QUINTIC Ball Roll

The QUINTIC Ball Roll System uses high-speed cameras to capture every detail of the ball and putter during the stroke. It tracks:

• Launch Angle: The vertical departure angle from the putter.

• Flight Angle: The actual trajectory after impact.

• Skid Distance: How far the ball glides before rolling.
• Time to True Roll: Duration to reach end-over-end rotation.

Key Insight: Launch vs. Flight AngleBy comparing Launch Angle and Flight Angle, coaches can diagnose if the ball is launching cleanly or interacting too long with the surface.

A small difference = Clean launch.A large difference = Grass interference and poor rollout.

Real Example

A player had a launch angle of 0.5°, but the flight angle differed by over 1.5°. The ball snagged on the surface and skidded inconsistently. After adjusting the player’s shaft lean and putter loft, the launch was improved to 1.5°, matching the flight angle—and the ball rolled smoothly with better control.

🎯 Summary

Clean launch = consistent roll.Launch angle between 0.75°–2.5° = optimal.QUINTIC helps players and coaches fine-tune stroke and equipment for predictable putting results.

Season 2 opens with a high-profile matchup between Atlanta Drive GC and New York Golf Club. The league features six teams composed of elite PGA TOUR players, including global stars such as Tiger Woods and Rory McIlroy. Instead of traditional individual stroke play, TGL is built around a head-to-head team format designed for speed, strategy, and entertainment.

At the core of the competition is the unique “Screen to Green” format. Players begin each hole by hitting long shots into a massive screen that displays a data-rich virtual golf course. Once within scoring range, play transitions to a first-of-its-kind physical short-game complex where shots are executed live. Despite the hybrid setup, every hole still requires the full range of traditional golf skills.

The virtual environment enables course designs that would be impossible outdoors. One standout example is the Cenote hole, inspired by limestone sinkholes of the Yucatán Peninsula, featuring deep water-filled caverns surrounded by jungle and stone. The system also allows for team-specific holes, strengthening team identity and fan engagement.

Technology enhances both competition and broadcast. Players are mic’d up, giving fans direct insight into strategy and emotion. A shot clock controls pace of play, while live data overlays modernize the viewing experience. With spectators in the stands and primetime broadcasting, the atmosphere feels closer to an arena sport than a traditional golf tournament.

In essence, TGL represents golf’s evolution into a digital-first, stadium-based competition—where elite skill, technology, and entertainment converge.

Elite putting performance is built on a data-driven framework that combines advanced diagnostics with disciplined execution. Technologies such as high-speed video analysis and ball-roll measurement systems reveal stroke mechanics and ball behavior that the human eye cannot detect. Successful putting goes beyond technical accuracy; it requires stable rhythm, reliable visual alignment, and the ability to perform under pressure. When physical mechanics, spatial perception, and mental control are trained together, players move from overthinking their stroke to executing with clear intent.

Modern diagnostics break the putting stroke into measurable components. Impact data reveals face angle at strike, start direction, and spin rate, while launch and roll metrics identify launch angle and skid distance before true roll begins. Even small deviations—such as a consistently open face by just over one degree—can explain repeated misses on longer putts. This objective feedback exposes issues related to excessive or insufficient loft, inconsistent launch, or prolonged skidding, allowing precise corrections instead of guesswork.

Putting physics is based on the motion of a rolling ball on an inclined plane. Physics-based models calculate the ideal line using four inputs: green speed (Stimp), slope percentage, putt length, and target speed. From these, three key outputs are generated: the ideal aim line, the distance point (where the ball should stop if it misses), and the total effective putt length. Ball speed is critical, as it directly affects forgiveness at the hole. At an optimal entry speed of roughly three rotations per second, the effective hole size is maximized. Faster speeds reduce forgiveness dramatically, making speed control a decisive scoring factor.

Data also corrects visual distortion. Many golfers believe they are aligned correctly when head or eye position creates a false perception. Objective measurements replace feel-based assumptions with reality, ensuring that setup, aim, and stroke match the intended physics model. Trying to putt without this feedback is comparable to navigating in fog without instruments—intuition alone cannot guarantee accuracy.

Execution is stabilized through rhythm training, most effectively with a three-beat metronome cadence: start, top of backswing, and impact. This structure regulates energy flow, prevents deceleration or rushed follow-throughs, and promotes even energy buildup with instinctive release. Rhythm is defined as motion without hesitation. By operating within a short, consistent timing window, the golfer minimizes conscious interference and allows athletic intent to guide the stroke.

Consistent scoring emerges from the combination of scientific diagnostics, physics-based targeting, and a disciplined routine. When modern data tools are integrated with structured rhythm training, putting becomes a precise, repeatable skill rather than a matter of feel or chance.

This guide explains how to execute spin-heavy chip shots by focusing on loft, strike quality, and turf interaction rather than force. On short shots, backspin is created primarily by loft at impact, not speed. Because chip shots lack the velocity of full swings, correct mechanics become decisive.

Loft is the single most important factor. Using a high-lofted wedge (typically 56–60 degrees) and preserving its natural loft through impact allows the ball to engage the upper grooves of the clubface. A common mistake is excessive forward hand press, which de-lofts the club, lowers launch, and reduces spin. Keeping the hands neutral ensures the clubface delivers sufficient loft for the ball to land softly and stop quickly.

Speed still matters, but differently than in full swings. Spin on chip shots depends on quality of contact, not raw acceleration. The stroke must be committed and crisp, with controlled acceleration through impact. Decelerating leads to poor groove engagement, inconsistent contact, and unpredictable rollout. Think of loft as the ramp and speed as the car: on a short runway, you cannot rely on speed alone, but the car must still drive confidently up the ramp without hesitation.

A shallow angle of attack is essential. Rather than chopping down steeply, the club should brush the turf, allowing the bounce of the wedge to glide along the ground. This sweeping motion improves consistency, prevents the club from digging, and promotes clean ball-first contact. Contrary to popular belief, a steep angle does not increase spin; it often produces fat or chunked shots and reduces effective loft at impact.

Maintaining loft, shallow contact, and steady acceleration work together. A steep attack reduces loft, compromises contact, and limits spin. A shallow motion preserves loft, enhances turf interaction, and allows the ball to “grab” the grooves properly. Much like skipping a stone across water, the correct angle lets the ball react and check instead of diving forward and running out.

By consistently applying these principles—neutral hands, high loft, controlled acceleration, and shallow turf interaction—golfers can dramatically improve spin control on chip shots and save more pars around the green.

Pelvis sway, the lateral movement of the hips, plays a fundamental role in creating an efficient, powerful, and healthy golf swing. Often described as the “engine room” of the body, the pelvis is the central hub where balance, force transfer, rhythm, and injury prevention come together. How well a golfer controls this movement directly influences ball striking, clubhead speed, distance potential, and stress on the lower back.

Pelvis sway is measured relative to the pelvis’s starting position at address, known as the zero point. For a right-handed golfer, the pelvis shifts slightly to the right during the backswing and then moves decisively to the left during the downswing and finish. This controlled side-to-side motion is not optional; it is essential for efficient biomechanics.

In the backswing, efficiency begins with a subtle lateral shift of the pelvis away from the target. This movement allows the golfer to load into the trail leg and build stored energy. Pressure develops under the right heel while overall balance remains stable and centered. This loading phase provides the foundation for speed and stability later in the swing. Problems arise when golfers lean their entire upper body instead of shifting the pelvis independently. That pattern leads to loss of balance, inconsistent contact, and wasted energy.

The most critical phase is the downswing and impact. Here, the pelvis must actively shift toward the target. This forward movement allows the golfer to push forcefully off the lead leg, converting interaction with the ground into power. At the same time, the pelvis moves slightly ahead while the chest stays back for a fraction longer, creating the X-factor stretch—the separation between lower- and upper-body rotation that drives speed. When this lateral shift is missing and the pelvis stays passive, clubhead speed drops, ball contact becomes inconsistent, and the lower back absorbs excessive stress due to unstable rotation. This pattern is also a common cause of slicing, as the upper body takes over and pulls the club outside the target line.

Pelvis sway also dictates the quality of the finish. In an efficient swing, the hips move clearly past the original address position toward the target, with the golfer balanced on the lead leg. This finish confirms that pressure was built, energy was released, and balance was maintained throughout the motion. If weight remains split between both legs or hangs back on the trail side, it indicates incomplete energy transfer and reduced swing efficiency.

Beyond performance, pelvis sway plays a decisive role in injury prevention. When the pelvis shifts correctly, forces are transferred through the ground and into the ball as intended. When it does not, the lower back is forced to compensate, increasing the risk of pain and overuse injuries. Proper lateral movement allows the body to work the way it is designed to work—powerful, stable, and resilient.

In simple terms, pelvis sway functions like drawing and releasing a bow. The backswing shift stores energy, and the downswing shift releases it. Without both phases, speed, control, and consistency suffer. Modern AI-driven analysis now allows golfers to measure pelvis sway precisely in each swing phase, replacing guesswork with objective data. This makes pelvis sway not just a concept, but a measurable key to better performance and long-term physical health.
