The Ball of the Century, also referred to as the Gatting Ball or simply That Ball, is the nickname given to a cricket delivery bowled by Australia's Shane Warne to England's Mike Gatting. The incident occurred on day 2 of the first Test of the 1993 Ashes series, which took place at Old Trafford, Manchester. On his first ball against England, Warne produced a spectacular delivery that bowled Gatting. - From Wikipedia, the free encyclopedia.
Murali's injured left shoulder hurt so much that each appeal turned his winsome grin into a wince of pain, yet on the second day, he still totted up 42 overs.

It pitched 18 inches outside leg, spat off the pitch and clipped the off bail. - From Wisden, the bible of Cricket.
