The 38-year-old Jamaican had smashed 17 sixes during his record-shattering 66-ball 175 not out for Royal Challengers Bangalore vs Pune Warriors in the 2013 IPL.Gayle shared an unbroken 201-run stand with former New Zealand captain Brendon McCullum who finished 51 off 43 balls. The Kiwi star hit three sixes which meant Rangpur Riders equalled RCB’s record of 21 sixes – the most by a team in an innings.He completed 11,000 runs in the shortest format of the game, and also became the first to score 20 centuries in T20s. He incidentally became the first player to blast 100 maximums in the Bangladesh Premier League.Gayle had last played international for West Indies in September and has not featured in a Test match since 2014.He was in poor form for RCB in the IPL this year, managing only 200 runs from 9 matches. However, his form in the BPL is certainly good news for RCB and it would be interesting to see whether they would still want to retain the West Indian or use their Right to Match card in the auction scheduled early next year.On December 8, Gayle had hammered an unbeaten 126 off 51 balls in the BPL Eliminator against Khulna Titans.Rangpur Riders went on to beat Dhaka Dynamites by 57 runs to lift their maiden BPL title.advertisementSohag Gazi, Isuru Udana and Nazmul Islam picked two wickets apiece for Rangpur as they restricted the Dynamites to 149/9 off their 20 overs.
