The bullet drive
It wasn't quite as picture perfect as his best straight drives, but Sachin Tendulkar produced a fine rendition of one of his signature strokes to lift himself out of a poor run in the tournament. He had made three off his first seven balls, but when Ravi Rampaul delivered a length ball outside off stump, a small and precise nudge forward preceded a measured swing through the line, and before mid off could even move, the ball had sped past him to the fence.
The red-herring stutter
Rarely do three top-order wickets fall in quick succession in a Twenty20 and have little effect on the match, but Mumbai Indians did not allow their mini-collapse to derail, or even delay their chase. Tendulkar edged one behind off Lendl Simmons in the 12th over, before Sunil Narine bamboozled Ambati Rayudu and Dwayne Smith in the next. But although Trinidad and Tobago seemed to have wrested back some momentum, Dinesh Karthik and Rohit Sharma wasted no time reasserting Mumbai's control, slamming two fours and a six in the next two overs to keep the innings running smoothly.
The delivery
It came too late to save T&T, but Sunil Narine's knuckle ball to dismiss Rohit Sharma in the 18th over was a reminder of his destructive ability in this format, as he reclaimed the top wicket-taker position in the tournament. The ball flew flat threw the air to pitch on middle, and anticipating little turn given the speed of the delivery, Sharma aimed a drive towards long on, playing a leg-stump line. Somehow, Narine had put plenty of spin on the delivery though, and it broke back sharply to evade Sharma's outside edge and take middle stump out of the ground.
The monster strike
Although two batsmen renowned for their aggression made half-centuries in the match, it was Darren Bravo who produced the biggest shot, when he hit Harbhajan Singh for six in the fourth over. Harbhajan floated one up on middle stump, and Bravo stepped down the pitch, meeting the ball with a big swing as soon as it had pitched. He struck it cleanly and sent it high into the night, on to the Feroz Shah Kotla roof.
