Surrey boosted by Clarke bowling

TWENTY20 CUP FINALS DAY Saturday, 30 July 1130 BST First semi-final: Surrey v Lancashire 1430 BST Mascot race 1500 BST Second semi-final: Leicestershire v Somerset 1915 BST Final Live commentary of all three matches on BBC Radio Five Live and this website

Surrey all-rounder Rikki Clarke expects to bowl again on Twenty20 finals day as the Lions seek their second title.

Clarke, who has taken 10 wickets in the tournament so far, has been struggling with hamstring trouble related to a problem with his pelvis.

He has not bowled in the current County Championship match against Nottinghamshire, which ends on Friday.

But he told BBC Sport: "It's basically precautionary - I've been playing as a batsman for the balance of the side."

Surrey play Lancashire in a repeat of last season's first semi-final, with the winner going on to meet either Leicestershire or Somerset.
