Chris Gayle smote 11 sixes in a match-winning 100 not out, setting various records in the process, as his accelerating masterclass gave West Indies a six-wicket win over England in their ICC World Twenty20 opener.
Gayle became the first player to hit 50 World T20 sixes before beating Brendon McCullum's mark of 91 T20 international maximums. By the end of the game he had 98 to his name.
The powerful West Indies opener made light work of overhauling England's 182 for six, albeit he had scored just 22 runs after eight overs.
Having played himself in, he went after England's bowlers with 75 more runs by the end of the 16th before going on to become the first person to make two World T20 tons. His innings occupied 48 balls.
England, put in by Darren Sammy, earlier rode on a smooth 48 from Joe Root plus handy contributions from Alex Hales, Jos Buttler and Eoin Morgan, who won his 57th format cap to become England's most capped player.
Yet the total proved insufficient as Gayle followed up Marlon Samuels' brisk 37 to leave Morgan's men needing to pick themselves up prior to Friday's meeting with South Africa, also at Mumbai's Wankhede Stadium.
England started defending their score well enough.
Although David Willey, getting significant swing, began with two leg-side wides, he then had Johnson Charles held at midwicket in an over that also contained two strong lbw shouts against Samuels.
Chris Gayle lays into the England bowling during an astonishing innings of 100 not out that featured 11 maximums
Gayle announced himself to Reece Topley with a four and a six back past the bowler. Samuels also struck Willey for consecutive boundaries in the next over.
Three more Samuels fours came in Ben Stokes' first over, albeit one via a Chris Jordan misfield, and the powerplay yielded 55.
Adil Rashid crucially struck in his first over, forcing Samuels to hole out to long-on, as the leg-spinner started tightly. However Gayle soon found his range against Rashid, consecutively launching two straight sixes high into the stands.
At 85 for two from 10 overs, West Indies were making similar progress to England, although Gayle accelerated the reply with successive pulled maximums off Stokes - the second putting him ahead of McCullum's record.
Moeen's economy was rewarded when Denesh Ramdin skied him to short-leg. And after Gayle again cleared the rope, Dwayne Bravo holed out to deep midwicket from a Topley full-toss, renewing England's hope.
Yet Gayle swung the game back in the Windies' favour with three sixes in a row, marring Moeen's previously impressive figures.
Two more maximums off Willey raced Gayle to 97. He then took his time in reaching three figures from 47 deliveries, squeezing Stokes to backward point for a single to register the landmark.
Victory came with 11 balls to spare and Gayle in the company of Andre Russell.
Joe Root gives England's innings some positive momentum with a typically assured 48 from number three
At the start of the match Hales and Jason Roy were initially kept under wraps, but Hales broke the shackles with three consecutive fours off leg-spinner Samuel Badree in the fourth over.
Although Roy fell in the next, chipping Russell to midwicket, Hales and Root kept up the momentum as 49 came from the powerplay.
Root soon hit the first six, emphatically pulling Russell flat behind square, while Sammy mixed up his bowlers, using six in the first nine overs.
With 81 on the board at the half-way mark, Root flicked his and England's second six over deep midwicket. However Hales then departed for 28, beaten by Sulieman Benn's yorker.
Buttler, initially listed at six, came in next and it was not long before he cleared the rope, smiting Badree over long-off.
Root attempted a similar shot off Russell, only to pick out mid-off, but Morgan responded by pulling the seamer into the second tier.
Buttler followed up with two leg-side sixes, the first in a productive Benn over worth 14, and the second off Bravo. Attempting another, this time from a Bravo full-toss, he picked out Carlos Brathwaite on the midwicket rope to depart for 30.
Stokes was quickly into his stride, with leg-side boundaries off Russell, before England smashed 18 from the final over thanks to maximums from Morgan and Moeen either side of Bravo trapping Stokes in front with a well-disguised slower ball.
