Three balls from a left-arm spinner, three big leg-side hits. They are not textbook pulls, and we say so. What they do share is easy to see in the frames: a wide base, an early set, a swing that goes all the way through.

The hit, in one picture
Five moments from the first hit, from behind the bowler. The skeleton lines are an automatic estimate of the joints on the flat picture, drawn to guide the eye. On a phone, swipe the strip sideways.

Watch the real thing first
This is the exact clip we analysed: SA20's own video of the three hits, on the official channel. Jump straight to each ball; the slow replays of the first two show the bat through the ball far better than any still.

Walk through it, one phase at a time
Keep scrolling. The picture follows the text.
Stance. Hit 1, behind the bowler. Footage: SA20 / Betway SA20.
01 · Stance
Set and still
Before the ball is released he is already set: knees soft, bat lifted and ready. Nothing is left to trigger once the ball is in the air, so the only job left is the decision.
02 · Backlift
Bat up, weight begins to settle
The bat reaches its high point early, while the ball is still coming down. He is not hurrying to get it there, which gives the swing a clean start.
03 · Weight shift
Feet open, room appears
By now the feet have moved apart and the base is wide. In these frames that is how he creates room: he opens out rather than leaning into the ball, so the arms have space to swing through.
04 · Impact
Wide base, braced front leg
At contact the front leg is planted and braced, and the bat travels across the ball from a stable base. The head stays steady while the body turns towards the leg side.
05 · Follow-through
Full finish, no check
The swing runs all the way through and the bat wraps high over the shoulder. There is no hold-back at the end, which is a sign he committed to the shot.
Three hits, one method
Same player, three balls, lined up at the moment of impact and played at half speed. The upright line drops from the back foot and the dot marks the head. If the picture looks nearly the same three times, that is the point: the habit repeats.

Where they fan out, the hit changes from ball to ball. The bottom row is foreshortened (the figure looks narrower from behind), so read it for repetition, not for shape.

Where it pitched, where it went
Two of the three balls were around a good length, and none was a short ball asking to be pulled. That is why we call these leg-side hits rather than pulls: they are hit across the line from a base that is wide and settled. Turn the pitch to see it from the bowler's end, or press play to watch the swing. The shaded fan is a broad leg-side zone read from the swing, not tracked ball flight.
Approximate · marked by eyeDrag to turn
Hand-marked from broadcast footage. Approximate. Right-handed batter. Length and line were judged by eye from the behind-the-bowler view; hit 3 is not marked because the camera zooms during the ball's flight. The green arc shows a lofted hit into the leg-side zone; its direction is read from the swing, not tracked. The batter's legs and hips (solid green) are an estimate from the behind-square replay of hit 1, from one camera, smoothed and placed at the crease by hand. That replay starts as the bat comes down, so there is no stance or backlift to show. The arms, body, head and bat (faded) are an illustrative leg-side swing, not taken from the footage.

The swing, one frame at a time
Scrub through hit 1 from the behind-square replay. The green arc traces the toe of the bat and draws itself as you go. It starts low, comes through flat and finishes high over the front shoulder: a full, committed shape, drawn from one camera as a path to look at, never as a number. Each phase you pass stays behind as a faint ghost of Klaasen himself.
Real footage · cut-outsDrag across the picture
Every figure is a real broadcast frame. Klaasen is cut out of each frame by software and laid over a clean background built from the same replay. The replay camera pans, so the frames are steadied in software; the slight depth as you scrub comes from layering the flat cut-outs (what we call 2.5D), not from a 3D model. The arc stops where the bat leaves the frame. Footage: SA20 / Betway SA20 (Durban's Super Giants v Paarl Royals, Kingsmead, 2024). Short excerpts used for commentary.

What a coach would take from this
Check the base firstWide and planted through contact. If it narrows or a foot lifts early, the power usually leaks with it.
Make room by opening up, not by lungingIn these frames the feet open and the front leg braces, which clears space for the arms. Look for that clearing in your own players.
Finish the swingFull follow-through, no hold-back. A shot that stops at contact is usually a shot that was half-decided.
Use it as a vocabulary, not a template. Hitting spin over the leg side is a high-risk shot, played here by an elite player late in a T20 innings. Every player's version depends on age, build, the ball and the situation.
