T20: Glamorgan's Dean Cosker eyes 'massive' Somerset game

Dean Cosker took career-best T20 bowling figures of 4-25 against Surrey

Glamorgan all-rounder Dean Cosker says it is crucial they win at Somerset on Sunday to boost their T20 Blast quarter-final hopes.

Friday's 19-run loss to Surrey in Cardiff saw Glamorgan drop to seventh in the South group with four wins from nine games.

But a win at Taunton would see Glamorgan leap-frog Somerset in fifth.

"It's a massive game at Somerset, it always is, the boys get really fired up for that duel," Cosker said.

"There's a huge rivalry with Somerset and Glamorgan, we're not going to take the game lightly - it's normally high scoring - we've done pretty well there recently over the last couple of years.

"The Twenty20 campaign is all about gaining momentum: we've gained momentum at the start of the competition but lost our way again.

"It's like a rollercoaster - all ups and downs - and hopefully we can turn it around next game.

"Every game is a huge game now on in, we're just over halfway in the competition ."
