“Knuckle ball (cricket)”的意思、由来-开放百科全书

In the sport of cricket, a knuckle ball (or knuckleball) is a type of delivery employed by a fast bowler, and a type of slower ball. As similar to a slower ball, the bowler's intention is to deceive the batsman into playing too early so that he either misses the ball completely or hits it high up in the air to offer an easy catch.

The ball is bowled by the bowler positioning the ball on the knuckles of his index and middle finger, instead of in the fingers themselves.

The delivery deceives the batsman as from a batsman’s perspective, the ball appears to be a stock delivery, however when it is released is slower than expected.

The delivery was adopted from baseball’s knuckleball. The physics of the operation are largely the same. However, the seam on a cricket ball is equatorial, and thus the extent of erratic movement is reduced due to the symmetry (at least in the conventional release position where the planes of the ball's trajectory and the seam are nearly co-planar). ^[1]

Bowlers who often use the knuckleball include India’s Bhuvneshwar Kumar and Australia’s Andrew Tye. Tye’s lethal use of the knuckleball leads to vast success in limited overs competitions, and his eventual selection for Australia. Tye’s fame is largely due to his world-renowned use of the knuckleball.^[2]
