JAKE Lehmann scored his maiden Yorkshire century in his last game for the county this summer as Somerset wrapped up a crucial Specsavers County Championship win by 10 wickets inside three days at Headingley yesterday.

Yorkshire and Somerset are now separated by a point in second and third place in the Division One table.

And they will now have to wait for the result of leaders Middlesex’s match against Lancashire to see their standing in the title race ahead of next week’s final round.

Middlesex are 72-4 in their second innings, leading by 140 ahead of today’s fourth day.

If Middlesex win, Yorkshire will be 20 points behind going to Lord’s next Tuesday, while a draw would be nine points and a defeat would leave the gap at just four.

Either way, it is safe to assume that Yorkshire, who enjoyed their best day of the week against Somerset yesterday, will need to win at Lord’s to have a chance of a third successive crown.

That is certainly how coach Jason Gillespie is viewing his last match in charge.

“We'll see what happens at Old Trafford, but I'm not going to worry too much about that result because we need to go to Lord's and win,” he said.

“We certainly need to go there with a real positive mindset, which we will be doing.”

Gillespie reported mixed availability news after the defeat, which was confirmed midway through the evening session as the visitors reeled in a target of 42.

Lehmann, who hit a superb 116, has been unexpectedly recalled by South Australia in order to prepare for their domestic season next month, and he will not be available.

But Steve Patterson will be after his father’s illness has improved.

Yorkshire enjoyed their best day of this fixture yesterday, but they had already left themselves with too much to do having been bowled out for 145 in the first innings to concede a lead of 245.

But Lehmann shared partnerships of 62 for the fourth wicket with Adam Lyth (49) and 101 for the eighth with Liam Plunkett, who made 73 in 286 all out.

Lehmann and Plunkett took the score from 162-7 with some aggressive batting either side of tea, including two sixes over long-on off Jack Leach’s left-arm spin for the latter.

Leach, however, had the last laugh. The buoyant spinner picked up each of Yorkshire’s last six wickets to fall, including Lehmann lbw sweeping and Plunkett caught at slip, on the way to figures of 6-64.

Left-handed Lehmann, whose father Darren scored a staggering 26 hundreds in 88 first-class appearances for Yorkshire between 1997 and 2006, admitted his disappointment at missing next week’s title decider.

“It’s a bit disappointing, but you can’t do much about it,” he said.

“The hierarchy want me to go back and play a couple of white ball games before the Matador (one-day) Cup.

“I’d love to go down to Middlesex and be with the boys because I’ve really enjoyed this experience.

“It’s nice to get a hundred, but it would be better to get one in a winning side.

“The game situation is always the one which matters the most.

“I’ve already looked at my phone, and there’s a message from my Dad. He’s always all over it. He knows what’s going on all around the world.”
