Everyone watches the drag-flicker. The short corner is actually won in the first second, in the inject and the trap — and if those two are clean, the strike almost takes care of itself.
The inject is a timing job, not a power job. The injector's only mandate is a flat, quick, accurate ball to the top of the circle at a repeatable pace. A fraction too hard and the trapper cannot control it; a fraction too soft and the defence is out. Practise it until the pace is boring and identical every time.
The trap is the hinge of the whole routine. The stopper's hands do the work: soft, low, and already angled toward the striking spot before the ball arrives. A dead trap that sits still is worth more than a fast one that skips. Most missed corners die here, not at the strike.
Only then does the striker matter. A drag-flick loads off the extra-low bow and whips low to high; a hit needs a clean, still ball and a full backswing the defence cannot read early. Either way, the striker is finishing work the inject and trap already did.
Drill the three in sequence, not in isolation. The magic is in the handoffs — inject to trap, trap to strike — and those only get smooth when you rehearse the whole chain under a runner's pressure.
