Craig White and Matthew Wood both thrashed centuries as Yorkshire enjoyed a run bonanza against Glamorgan at the Scarborough Cricket Festival today.

Yorkshire finished the second day strongly placed on 433 for five, their first innings lead over Glamorgan being worth 210.

In an early celebration of clinching the CricInfo Championship title - now a mere formality - White and Wood piled up 243 in 63 overs for the second wicket.

Wood, who rejoined White at the crease in the first over of the day after retiring hurt last night, cracked 124 off 240 balls with 18 fours and two sixes before falling lbw to left-arm spinner Dean Cosker.

But White continued to plunder runs off the Glamorgan attack and he was in sight of a maiden double century when his off stump was removed by Darren Thomas for 183 which included 25 fours and two sixes and was made off 273 deliveries.

It was Wood's fourth century of the season while White was left just three runs sort of equalling his career-best score which he set up a fortnight ago in the Roses match at Old Trafford.

The 6,000 crowd were expecting some early fireworks from Darren Lehmann when the Australian came in at 353 for three but after making only a single he launched himself into a big drive and lobbed back a catch to Cosker during the spinner's marathon spell.

Michael Vaughan made an elegant 45 before chopping Steve Watkin into his stumps but Anthony McGrath and captain David Byas settled in together to cause Glamorgan more grief.

A big cheer went up when Byas pulled Simon Jones for the boundary which took Yorkshire to 400 and secured maximum bonus points - so guaranteeing them the title if they go on to win the match - and Byas celebrated the moment by hooking the next ball for six.

McGrath was unbeaten on 29 and Byas 31 at the close, the sixth wicket pair having put on 59 together.

Wood said later: "I had six stitches put into my cheek after being hit but it could have been a lot worse and I just wanted to get back in the middle. Once I had struck that early six I felt much better and really enjoyed my partnership with Craig."
