1 Executive summary

Bottom line: a clean, athletic hybrid strike. The ball is a yellow streak one frame after contact, the hands return exactly to their address spot, and the finish is full and balanced. The swing is compact (three-quarter top) with a ~0.57 s backswing and ~0.32 s downswing (~1.8:1).

The same head pattern seen in his irons is here: the cap drops ~6½ in by the time the lead arm is parallel and is ~7½ in down at impact, with the hips rising ~2 in. Keeping the head on its line is the main lever for a longer, more repeatable hybrid.

Baseline

First 3-hybrid

Every future hybrid report will be compared against these numbers.

Priority 1

Quiet takeaway

The cap drops in the first 0.3 s. Keep it on its line until the lead arm is parallel.

Priority 2

Fuller backswing

Same downswing, a slower and slightly longer backswing toward 2.5–3:1.

2 Ball flight

Crystal Springs has no launch monitor on this bay, so there's no ball data for this swing (same as his Driver #3 and Pitching Wedge #2 from this session). From the video: solid contact, ball off the mat cleanly, launched immediately (gone within 1/30 s).

Reference only: PGA Tour hybrid averages (TrackMan) are ~102 mph club speed, ~146 mph ball speed, ~10° launch and ~225 yds carry. Next time at Mariners Point, a few 3-hybrid shots on the range screen would complete this baseline.

3 Timing & tempo — measured from the video

30 frames per second, so each time is accurate to about ±0.03 s. Takeaway starts at ~9.05 s, the club reaches the top at ~9.62 s, and impact is at ~9.94 s.

GroupBackswingDownswingRatio
André (3-hybrid #1, Oct 11)~0.57 s~0.32 s~1.8:1
André (Driver #3, same day)~0.63 s~0.27 s~2.3:1
André (Pitching Wedge #2, same day)~0.60 s~0.22 s~2.8:1
PGA Tour (Tour Tempo, "24/8")~0.80 s~0.27 s3:1

Tour figure: John Novosel, Tour Tempo. Frames: takeaway 47, top 64, impact between 73 and 74.

What it means: the backswing is about the same length as his driver's and wedge's that day, but the downswing is a touch slower (~0.32 s vs 0.22–0.27 s). That fits the compact top: less coil to unwind. A slightly fuller turn lets the downswing get quicker without forcing it.

4 The reference frame — how this swing was measured

Reference frame
  • Grid: each square is about 5 inches (~9 px per inch at the golfer), scaled from his hip-to-ankle length, so treat distances as ±1–2 inches.
  • Vertical center line (light green): the head's address position. Horizontal lines: cap height (white) and hip height (light green) at address. The white box is the head at address: in this impact frame the cap sits well below it.
  • Two corner diagonals (green): a fixed perspective scaffold for depth.
  • Paths: the red trail is the head and the yellow trail is the hands, frame by frame from address to impact. The red circle is the ball's address spot (ball just launched in this frame).
  • Body points were tracked automatically on every frame (92 frames, 7.5–10.6 s), head height was read from the top of the cap, then checked by eye at each key position. The camera is fixed.

Impact frames

6 Position-by-position biomechanics

Club: 3-Hybrid. Logged as report #1.

Photo 1 — Address Good

  • Athletic posture, weight centered, ball just forward of center for a 3-hybrid, played off the mat (the rubber tee sits empty beside it).
  • Two-stick station: one along the toe line, one marking the ball position.
  • Very still over the ball: the cap holds its line for the 1.5 s before takeaway.

Photo 2 — Takeaway Watch

  • One-piece start: hands, arms and chest move together, club low to the ground.
  • The cap is already ~2 in lower after 0.17 s: the dip starts with the first move.

Photo 3 — Lead arm parallel Watch

  • Lead arm parallel at ~0.30 s, wide and on plane.
  • The cap is ~6½ in below its address line and the head has moved ~5 in toward the ball, the largest head move of the swing.

Photo 4 — Top Good

  • Compact, three-quarter top (~0.57 s backswing): shaft short of parallel, which suits a hybrid.
  • The head rises back to ~4 in below address; hips ~5 in back from the ball as they turn.

Photo 5 — Arm parallel (down) Good

  • Arms drop in front of the chest with the lower body leading, club on plane.
  • The head starts sinking again into the strike.

Photo 6 — Delivery Good

  • Hands almost back to the ball, shaft still lagging: stored speed for impact.

Photo 7 — Impact · ball launched Head down

  • Strike between frames 73 and 74 (~9.94 s); in frame 74 the ball is already a yellow streak leaving the mat.
  • The cap is ~7½ in lower than at address and ~2½ in toward the ball.
  • Hips ~1½ in back from their address depth (no early extension) but ~2 in higher.
  • Hands back to their address spot.

Photo 8 — Release Good

  • Arms extend toward the target, chest rotating through, trail heel up.

Photo 9 — Finish Excellent

  • Full, balanced finish facing the target, weight on the lead side, trail toe up (last frame of the clip).

7 Same day, three clubs (October 11, Crystal Springs)

Club (Oct 11)TempoHead at impactHips at impact
3-Hybrid #1~1.8:1~7½ in down, ~2½ in toward ball~2 in up
Driver #3~2.3:1~5 in down, ~5½ in toward ball~3 in up
Pitching Wedge #2~2.8:1~4–5 in down—

Same pattern with all three clubs that evening: the head drops into the ball. The hybrid shows the deepest dip but the smallest move toward the ball, and the hips rise less than with the driver.

8 Diagnosis

  1. Fast, early head dip (~6½ in by lead arm parallel, ~7½ in at impact): the common thread across his irons and woods.
  2. Hips hold depth: ~1½ in back at impact, no early extension; a slight ~2 in rise.
  3. Compact top, tempo ~1.8:1: quick backswing, slightly unhurried downswing.
  4. Contact: clean strike off the mat, ball launched within one frame, hands back to address.

9 Next steps — keep it simple

1

Quiet takeaway

First 2 ft of the backswing with the cap still: turn the chest, don't bow toward the ball. 10 slow takeaways, then full swings.

2

Fuller turn

Let the backswing finish (lead shoulder under the chin) before starting down. Target ~2.5:1.

3

Get the numbers

Hit a few 3-hybrids on the Mariners Point screen to add ball speed, carry and launch to this baseline.

10 Limitations & next capture

Confidence: high on tempo and positions; moderate on head and hip distances.
