A frame-by-frame review of today's 7-iron swing at Mariners, hit from a three-stick alignment station with a towel marker, plus the full ball-flight readout from the range screen. It covers set-up, tempo, head motion, impact and ball flight, and closes with simple next steps.

1 Executive summary

Bottom line: a very good 7-iron. 147 yards total, 144 carry, and a curve of 0 feet: the straightest shot in André's whole logbook. Ball speed was 104 mph, exactly the LPGA Tour 7-iron average, and the carry beats that average by 3 yards. The set-up station (feet stick, target-line stick, ball-position stick and towel) did its job.

What's left is the same pattern as his other irons: the launch is high (22° vs a 15–18° window), the head drops about 5 inches by impact, and the tempo is about 2:1. One more finding: this 7-iron flew almost as far as his 6-iron (149 total), so the gap between the two clubs is only 2 yards.

Strength

Dead straight

0 ft curve, 47 ft from the target, with a full, balanced finish.

Priority 1

Stay tall

Keep the head at its address height through impact. It's also the key to a lower launch.

Priority 2

Flight it down

Hands ahead at impact, aiming for an 18–19° launch and more carry.

Flat carry (elevation-adjusted) showed 143 yds. Club speed isn't on the screen; at a typical 7-iron smash of ~1.33–1.37, 104 mph ball speed means about 76–78 mph of club speed, right at the LPGA average (76 mph).

What it means: his ball speed and carry already match a tour-level women's 7-iron. The ball comes out about 3° higher than that benchmark, though. Turning some of that height into forward speed (more shaft lean) is worth roughly 5–8 extra yards.

3 Timing & tempo — measured from the video

30 frames per second, so each time is accurate to about ±0.03 s. Takeaway starts at 36.47 s, the top is at 36.93 s, and impact is at about 37.17 s.

GroupBackswingDownswingRatio
André (7-iron, today)~0.47 s~0.23 s~2:1
André (PW #2, Oct 11)~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. One frame either way moves the ratio between ~1.8:1 and ~2.3:1.

What it means: the downswing speed is the same as his best wedge, but the backswing is shorter and quicker, so the ratio is back to his usual ~2:1. The 2.8:1 from the wedge came from a slower, fuller backswing. That's the piece to carry over to the longer clubs.

5 Position-by-position biomechanics

Set-up station

Alignment station

The white stick runs along the feet line, parallel to the target. The second stick is the target line just past the ball, and the cross stick marks the ball position in the stance. The towel sits at the ball, as a visual marker and to catch a steep or outside-in strike.

P1 — Address Good

  • Feet parallel to the white stick, so the body lines up square to the target line.
  • Athletic posture: knees flexed, back straight, arms hanging under the shoulders.
  • Ball at the cross stick. The exact spot between the feet can't be judged from this angle.

P2 — Takeaway Good

  • One-piece start: arms, hands and club move away together.
  • The club stays outside the hands, with no early inside roll.

P3 — Lead arm parallel Good width

  • A wide arc, with the wrists setting on time.
  • The trail knee keeps its flex, which is a stable base.

P4 — Top High hands

  • Full shoulder turn, with the hands finishing above the head.
  • The head sits about 3 inches lower than at address.
  • The shaft stops short of parallel, which is a good length for control.

P5 — Lead arm parallel (down) Good

  • The wrist angle holds as the arms drop.
  • The lower body starts the downswing.

P6 — Delivery Solid

  • The club comes down from the inside, along the target-line stick.
  • The arms stay in front of the chest.
  • This path is why the ball didn't curve at all.

P7 — Impact Watch the head

  • Clean strike: 104 mph ball speed and 0 ft curve.
  • The head is about 5 inches lower than at address and ~1–2 inches closer to the ball.
  • The hips move slightly toward the ball (about 2 inches), a mild early extension. It fits the high launch.

P8 — Release Full extension

  • Both arms extend down the target line.
  • The chest keeps turning.

P10 — Finish Excellent

  • Tall and balanced on the lead leg, with the trail foot up on its toe and the belt buckle facing the target.
  • Held, as in every report.

Overlay — head at address, top and impact

The white line is the top of the cap at address, and the gold line is the back of the head at address. The camera didn't move. Distances are estimated from his body size in the frame, so treat them as ±1 inch.

7-Iron · today147 yds144 yds104 mph22°0 ft

Heads-up: today's 7-iron carried 4 yards farther than the 6-iron did on Oct 6, and the totals are only 2 yards apart. A normal gap is 10–15 yards. The 6-iron launched even higher (23°), which cost it distance, so it likely has more to give. A 6-iron with ball data next will tell us.

7 Diagnosis

  1. Direction is solved for this swing: square station, inside delivery and 0 ft of curve.
  2. The head dips about 5 inches, starting in the backswing. It's the same "sinking" seen in his driver, 4-, 5- and 6-iron and wedge videos. To find the ball from a lower head, the body has to stand up through impact, which adds loft. That explains the 22° launch.
  3. Tempo is back to ~2:1. The wedge proved he can make a 2.8:1 swing, and the difference is a slower backswing.

Confidence: high on ball flight (range screen) and tempo (measured); moderate on head and hip distances (estimated from body size).

8 Next steps — keep it simple

Priority 1 · Stay tall

Cap-on-the-line check

Same camera spot as today. Mark the top of the cap at address on the screen, then hit 10 balls trying to keep the cap on that line until the ball is gone.

Feel: "chest stays over the ball, knees keep their flex."

Priority 2 · Launch

Hands-ahead punch

Hit five half-swing 7-irons with the hands ahead of the ball at impact and a short, low finish. Watch the screen: aim for 18–19° launch.

Lower launch with the same speed means more carry.

Tempo

Wedge rhythm, longer club

Count "back-2-3, down-1", the same count as the 2.8:1 wedge swing.

Slows the backswing without slowing the downswing.

Keep

The full station

Feet stick, target stick, ball stick and towel for every club.

It produced the straightest ball in the logbook.

9 Limitations & next capture

Next session: 5 balls with the same club for an average, a face-on view at chest height, and a 6-iron with ball data to settle the gap.
