Somerset had worked their way into a strong position by the end of an incident-packed second day of their Cricinfo Championship match with Yorkshire at Headingley.

They stood on 101 for one in their second innings, giving them an overall lead of 127.

The situation could have been much worse for Yorkshire, however, because a three-wicket burst by Andy Caddick in the morning left them reeling on 35 for four.

In addition, Darren Lehmann was struck on the right index finger by Caddick and had to go to hospital for a precautionary X-ray which showed bruising but no break. The Australian later returned to the fray and hit a dashing 38 from 37 balls with eight rasping boundaries.

The main repair work for Yorkshire, however, was done by Michael Vaughan and Gary Fellows in a positive fifth-wicket stand of 125, Fellows completing his first Championship half-century before falling lbw to Graham Rose for 63 off 119 balls with eight boundaries.

Vaughan's innings was a blend of careful concentration and fine strokes and it ended on 79 when his drive at Caddick was well caught low down at cover point by Michael Burns. He had received 180 deliveries and hit 12 fours.

The Yorkshire innings closed on 231 to trail Somerset by 26, Caddick taking five for 81 and receiving sound support from Steffan Jones with three for 37.

Piran Holloway and Marcus Trescothick began Somerset's second innings at a rattling pace, the pair including ten boundaries in their first 50 runs together, but when Trescothick had contributed 31 out of 63 he hit back a left-handed catch to Lehmann in the slow bowler's second over.

Soon afterwards, Trescothick was back in the middle as a runner for Holloway, who was limping badly. The batsman was still able to move to his 50 off 95 balls with ten boundaries and at stumps he was unbeaten on 58.
