Watch highlights of day three
Yorkshire opener Adam Lyth celebrated his 27th birthday with yet another fine batting display on the third day of the new title-holders' LV= County Championship match against Somerset at Headingley.
Lyth, Division One's leading run-scorer, signed off the season with a cleanly-struck 51 to give him 1,489 runs at an average of 67.68 - but he left Yorkshire with some work still to do in their bid to save the match.
They will resume on the final day on 148 for two, 36 runs behind, and will be anxious to preserve their unbeaten home record before the White Rose Club present the championship trophy in front of their home supporters.
Lyth ended his splendid campaign as he began it - with half-centuries against Somerset. In between, he plundered two double-centuries, four tons and a further four fifties.
After Somerset moved their overnight from 319 for three to 437 all out to give themselves a first innings lead of 184, Lyth opened up Yorkshire's reply with Alex Lees - who has also enjoyed a magnificent summer.
Lees reached 23 shortly before he pushed defensively at Peter Trego and feathered a catch to wicketkeeper Craig Kieswetter to leave Yorkshire on 44-1 in 12 overs.
Gary Ballance began soundly enough but he had an escape on 24 when he mis-timed a pull at left-arm spinner Jack Leach and Jamie Overton spilled an easy catch running towards square leg.
Shortly after tea, Lyth off drove Leach for his eighth boundary to reach his 50 and then mis-timed his pull at Trego to hole out to Tim Groenewald at mid-on.
Ballance, partnered by Joe Root, sealed his own successful summer for both county and country by making his 50 from 102 balls with four boundaries, but the light quickly closed in and the players came off with 17.4 overs of the day's ration still remaining.
In the morning, 20-year-old Somerset rookie, Tom Abell, added four to his overnight 71 before Jack Brooks found enough movement to have him caught at second slip by Lyth and when nightwatchman Leach was dismissed by the industrious Steven Patterson for a cleanly hit 43, Somerset were 364 for five.
Lyth gone! He's clothed a pull to mid-on off Trego, 51. 121-2. Ends the season with 1,489 Championship runs.

Trego dashed his way to 41 from 30 balls with four fours and two sixes but the second half of the batting swiftly crumbled to Adil Rashid, who grabbed four wickets in 14 balls while conceding only five runs.
The leg-spinner ended with 4-116 but much of the hard work was done by Patterson, who deservedly returned his season's best figures of 4-54.
Lyth said: "I got a few hugs on the field this morning from team-mates who had still to wish me happy birthday!
"It felt good to end the season with another half-century but it would have been an even better birthday present if I could have got an extra 11 runs to finish up with 1,500."
Lyth, who has been included in the squad for England's Performance Programme visit to Sri Lanka, added: "I am very happy with how it has gone for me this season and hopefully the winter will turn out to be just as good if not even better.
"It feels great to have scored runs and taken catches this summer but being part of the championship-winning team means even more to me."
"It would be nice now if we can bat for a long time tomorrow and if we do well enough we may be able to leave Somerset with a difficult 25 or 30 overs to face themselves."
