Yorkshire's chances of avoiding the follow on were dealt a severe blow at Scarborough today when Craig White was out off the final ball of the first over from left-arm paceman Matt Bulbeck.

Anthony McGrath and Darren Lehmann then rallied Yorkshire from 50 for two but Lehmann benefited from twice being put down.

The third day began with Yorkshire on 46 for one and still requiring 303 to reach their safety figure of 349 but disaster struck after White had scored a couple of twos off Bulbeck to take his overnight score on to 19. He shouldered arms at a swinging delivery which uprooted his off-stump.

The wicket to go down last night was that of Matthew Wood who showed some dissent when given out lbw to Bulbeck.

Umpire John Holder did not report Wood but he did have a quiet word with the batsman later on.

Skipper Lehmann, York-shire's only in-form batsman joined McGrath and after Lehmann had driven Graham Rose for four McGrath smacked Bulbeck to the cover boundary.

McGrath looked far less assured, however, when his inside edge against Bulbeck narrowly missed his off-stump and there was double luck for Lehmann at the other end - much to Somerset's despair. First he appeared to be dropped by wicketkeeper Rob Turner down the legside off Rose and later in the over he sliced a drive and Peter Bowler at first slip grassed a fast chest high chance.

Somerset occupied the crease for 165.1 overs yesterday.

Rob Turner and Keith Dutch patiently built up their seventh wicket stand against uninspired bowling and even though Dutch twice in one over drove fours over mid-on at Richard Dawson's expense Somerset were only 359 for six at the 130-overs stage.

Dutch was eventually lbw to Dawson for 74 off 148 balls, his partnership with Turner being worth 130 in 46 overs.

Turner followed second ball after tea when bowled round his legs by Sidebottom for 63 from 175 deliveries.

At 453 for eight, Somerset began to move along more smartly and there were two sixes for Matt Bulbeck and one for Rose before Rose came down the track to Dawson and was stumped for 24, the dismissal prompting the declaration.
