Finch injured in Twenty20 defeat

The Victorian batted on in vain as Surrey fell to Birmingham in a run-fest

Solid contributions from Surrey's Australian limited overs players Aaron Finch and Moises Henriques haven't been enough to stop Birmingham Bears reaching the T20 Blast Finals Day for the third time in four years.

Match report: Birmingham beat Surrey

Jason Roy's 74 off 38 balls and meaty hitting from Henriques (48) and Aaron Finch (39) had propelled Surrey to a total of 5-204, the second time they have posted more than 200 in this season's competition.

It was a score that led to injured Surrey batsman Kevin Pietersen tweeting to ask if they could declare.

But Bears' skipper Grant Elliott and fellow New Zealander Colin de Grandhomme steered them to a six-wicket victory by adding 64 off 38 balls as they chased down their target with four balls to spare to stun the majority of a 12,473 crowd.

Finch defied a calf muscle injury to put Surrey into what appeared to be a winning position.

The Victorian and fellow opener Roy had already put together two century stands in this season's Blast and this time added 98 from 55 balls.

Finch had to bat with a runner after pulling a calf muscle in the second over but it did not inhibit him too much as struck five fours and two sixes before holing out to long on.

Birmingham will fancy their chances of repeating their 2014 success on their home ground at Edgbaston.
