SYDNEY: West Indian opener Chris Gayle went out with a bang in the Big Bash League, smashing the equal-fastest 50 in Twenty20 history. The burly Jamaican equalled Yuvraj Singh’s 50 off 12 deliveries for India against England at the 2007 T20 World Cup in Durban. Gayle needed a six to reach the record and it was not a problem against the Adelaide Strikers on Monday night. He slogged four successive sixes in the first over. The onslaught carried on in the third over as Gayle belted 22 to reach 44 from 11 balls. He was finally caught skying a catch off Travis Head on 56 off 17 — the fastest 50 in BBL’s five-year history.
