Somerset 252 (Petersen 54, Trescothick 53, Bresnan 4-76) and 61 for 6 (Brooks 4-22) drew with Yorkshire 505 for 9 dec (Rashid 180, Ballance 107)

For a short while this evening Jack Brooks, the "Headband Warrior", and Steve Patterson breathed life into what looked like a dead contest, and even hinted at another remarkable Yorkshire victory. Almost repeating his feats from last week against Derbyshire, Brooks took four Somerset wickets in his first four overs as the visitors followed on.

In Brooks' fifth over he injured his left thumb fielding a drive off his own bowling and left the field immediately. Patterson replaced him and wasted no time in adding to the pressure on Somerset by taking two wickets of his own.

But Marcus Trescothick stood firm while his side crumbled around him and a match in which 120 overs were lost to rain and bad light ended in the draw that seemed the most likely result at the start of a day in which the first two-and-a-half hours were washed away.

When play finally got under way at 2.10pm, Andrew Gale gave the ball to Patterson at the Football Stand End, and he struck with his second ball. Jos Buttler hung his bat outside off stump to give Andy Hodd a simple catch behind the stumps. James Hildreth didn't last much longer. He looked promising, whacking Rich Pyrah's first two balls to the off side boundary, but then authored his own demise by flat-batting Pyrah to Adil Rashid at point.

Peter Trego stayed for 40 minutes but then tamely steered a Patterson ball to cover. Alfonso Thomas and Steve Kirby set about restoring some order, while Gale set attacking fields for Tim Bresnan and Rashid. The batsmen made it through to tea, but didn't survive long afterwards. Thomas brought up a second batting bonus point with a top-edged cut to the boundary, but immediately afterwards Bresnan struck. He has bowled excellently throughout this match, and was very quick on Friday. First Kirby edged a fast-rising ball to slip and the next delivery was simply too rapid for Jamie Overton.

Yorkshire enforced the follow on with 25 overs left in the day, reduced to 23 by a shower. Brooks' wicket celebration has already become legendary at Headingley, and the crowd were treated to it four times in a few minutes. He had Nick Compton and Alviro Petersen snaffled by Adam Lyth at second slip - Compton for a duck - then removed the off stumps of Hildreth and Arul Suppiah, who completed a pair.

When Brooks retired to the pavilion nursing his thumb, with a wicket-taking spell of 4 for 22 in 25 balls behind him, Patterson proved a more than adequate replacement, finishing with figures of 2 for 4. Buttler played a loose shot and was caught at first slip, then Trego was lbw to a ball that shot through. But throughout the mayhem, Trescothick stood firm, never looking in trouble, and guided his team to safety.

Yorkshire's coach, Jason Gillespie, was full of praise for his side at the end of play. "I thought our seam bowling was excellent all game. Our batting, after being 75 for 4, to finish 505 for nine was brilliant, the way they went about it." Gillespie is big on positivity and "intent", telling his players that someone arriving at the ground who hasn't yet seen the scoreboard should look at them and assume they're on top.

These sides meet again in the YB40 on Saturday. If there is such a thing in sport as momentum, then it's with Yorkshire but, as Gillespie stressed, Somerset are a very good side, and the one-day game is different to Championship cricket. Brooks will almost certainly not be playing as he was sent to Leeds Royal Infirmary for an X-ray.
