County Championship: Somerset slump against Surrey after superb Peter Siddle spell

Australian Peter Siddle has taken 13 wickets in three games for Somerset so far this season

Australian Peter Siddle marked his 200th first-class game with six wickets before a Somerset collapse left the game in the balance at The Oval.

Surrey reached 308 all out, adding 104 to their overnight 204-5, as Siddle cleaned up the tail to return 6-51.

Jamie Overton produced the ball of the day, an inswinging yorker, to bowl Somerset opener Matt Renshaw for 10.

And although Tom Abell (53) and Tom Banton (52) batted well, Somerset were 196-9 at the close, 225 ahead.

There was a worrying moment for Surrey and England followers when Ben Foakes collided with Jamie Overton as he dived across to take the catch to dismiss Banton off Reece Topley (3-49).

It left the wicketkeeper lying on the ground but he was eventually able to walk unaided to the boundary, with Ollie Pope taking over behind the stumps.

Sam Curran top-scored with 80 in Surrey's first innings, again falling short of an elusive maiden century when he was caught at second slip off Siddle.

But the home side were only 29 behind when they were finally all out and then removed both Somerset openers with only 43 on the board.

Abell - who made a career-best 150 not out in the first innings - and Banton added 89 for the third wicket before the former edged behind off Ryan Patel, the second of four catches taken by Foakes.

From 132-2, Somerset declined to 158-7 and Surrey claimed two more wickets before the close, with Pope catching Siddle off Jordan Clark (3-48) from the final delivery of the day.

Surrey bowling coach Azhar Mahmood told BBC Radio London:

"Ben Foakes took a blow to the neck and shoulder and has a small cut near his ear. He's under observation in the dressing room from our physios and he'll have a concussion test. But we hope he'll be feeling ok and can get back into the game.

"James Taylor had a back spasm and could not bowl, and Sam Curran is limited to 15 overs in the game and we didn't want to take a chance on him bowling just five overs after he had batted so well for his 80."

"After tea the bowlers did an absolutely brilliant job and really stuck to their plans well after we got the crucial wicket of Tom Abell."

Somerset batting coach Lachlan Stevens:

"The ball started to move around more in the air when the lights were on later in the day but we've batted pretty well in the conditions, led by Tom Abell in our first innings.

"Tom Banton also batted very well, in both innings, and Tom Lammonby did well opening up before he nicked one down the legside, which was unfortunate.

"The game is in a very interesting position. It's a great cricket wicket. Hopefully we will have enough runs on the board to give our bowlers a good chance of winning."
