Gayle smashes 12-ball fifty to equal world record of Yuvraj Singh
Left-hander Yuvraj achieved the feat against England in a group match at the inaugural World Twenty20 in 2007 in South Africa, smashing fast bowler Stuart Broad for six sixes in one over.
Opening batsman Gayle plundered 21-year-old Adelaide Strikers bowler Greg West, playing his second T20 match, for 27 runs in the first over and hit the last four deliveries for six.
His seventh maximum took Gayle past his half-century as he deposited spinner Travis Head over the long-on boundary.
Head dismissed him five deliveries later for a 17-ball 56 with Gayle caught by wicketkeeper Tim Ludeman from a top edge.
