Third T20 at Rajkot on Tuesday (13:30 GMT)
by Tom Rostance & Timothy Abraham
Tilak is in the zone now, flicking away Brydon Carse's first ball for another six before he scampers a quick single. He has raced to 26.
That Tilak Varma six was clocked at 82 metres - that's about 90% of Big Ben. Some hit...
India chasing 166
Six more! A bit of luck this time as the pace of Jofra Archer is top edged over the top of the keeper for six more to Tilak. That brings up the 50 for the chasing hosts.
That'll help India though! Tilak steps to leg side to give himself room and the chops away a fast ball from Jofra Archer for four.
His next shot is MAGNIFICENT! Down on one knee to a rapid ball, he slog sweeps Archer for a huge steepling six over fine leg. That's enormous.

This is scintillating stuff from Wood. Sustained, hostile pace bowling.
India need 132 off 96 balls. Well poised this.
Fetch that! Mark Wood spears in but too straight and India captain Suryakumar Yadav gets his blade to it and clips it over the man at square leg and the ball disappears for four more.
India need 166 to win
Tilak tries to ramp Mark Wood and misses the ball but gets a wide. Hard to know where to look at the moment, nervous tension at the crease.
Wood then wings a bouncer past the nost of Tilak. He is shifting!
Captain Suryakumar Yadav comes in and clobbers his first ball for four square on the off side. The crowd enjoyed that one!
Suryakumar then plays a lovely late cut off a slower ball, spanked away for another four. Great hands from the skipper.

Jofra Archer vs Suryakumar Yadav in T20s: 29 runs, 28 balls, 3 dismissals, 9.6 average, 103 strike rate.
Plenty of reason for Buttler to keep his strike bowler on for a third over here.
Samson c Carse b Archer 5 (Ind 19-2)
Sanju Samson never looked comfortable against Jofra Archer and he falls in cheap fashion. Again it's short of a length and quick, he fends it off but it never looks like going for six and is basically chipped up to Brydon Carse.
Great start for England.
India chasing 166
Samson can't get one away from Jofra Archer, England's two quicks looking exactly that in these early stages. He then flicks one away but not very convincingly, just over the man at square leg.
That was high on the bat but he gets a couple.
Tilak Varma is the new man in and tickles another quick straight one away for a single, Wood is on the deck after delivering the next ball in trademark style. He gives every ball everything he's got.
Top over for England.
Abhishek lbw b Wood 12 (Ind 15-1)
Got him!
It looked dead out at real speed and no matter how many replays they show there's nothing to save Abhishek Sharma there. Pinged on the back leg. Pure pace.
Howwzzaattt! Wood swings one in and the finger goes up for lbw but India have sent it upstairs...
Mark Wood's first ball is a beauty, shaping away from Samson as he doesn't play a shot. He then jabs it away for a single, I'd be getting off strike too. Wood hurling it in.
Shot! That's brilliant from Abhishek Sharma!
He makes room, stepping outside leg stump and then clobbering Jofra Archer for a flamboyant four over extra cover.
Superb shot. And then four more, slightly edgy but always safe.
Jofra Archer bangs it in short and Samson gloves it away for a sharply-taken single before Archer beats the bat of Abhishek.
He looks sharp! But the batter just leans on the next ball and chips it over the field for four.
Sanju Samson and Abhishek Sharma are out in the middle, Jofra Archer with ball in hand...
It's approaching 9pm in Chennai and the atmosphere for this chase is going to be deafening I'd imagine.
Are England up for the challenge?
