Matthew Wood rapped out his first century of the season in an unbroken second-wicket stand of 161 in 39 overs with Anthony McGrath as Yorkshire made up for lost time on the first day of their championship match with Derbyshire at Headingley yesterday.

After the morning session had fallen foul of the weather, Yorkshire stood on 225 for one when bad light and then rain ended play for the day with a further eight overs remaining.

Wood was exactly 100 not out from 184 balls with 15 fours and two sixes, while McGrath had struck a chanceless 89 off 114 deliveries with 13 boundaries.

Yorkshire gave a second championship appearance to 18-year-old leg-spinner Mark Lawson, while Derbyshire had a debutant in off-spinner Chris Paget, who at 16 years and 283 days was the county's youngest ever player in the competition.

Wood was happy to win the toss on a good batting pitch - the same one that was used for the floodlit game earlier in the week because the intended strip was too damp - and he and Andy Gale quickly settled into a productive opening partnership.

Wood began with some well-timed cover drives which brought him the first 19 runs scored but Gale soon began to thrive on the legside as he narrowed the gap with his captain and he had made 29 out of 64, Yorkshire's second highest opening stand of the season, when he moved across his stumps to Jon Moss and was lbw.

Progress was maintained with the arrival of McGrath who plundered 174 in his last championship innings against Derbyshire followed by an unbeaten 96 the following day off Middlesex Crusaders.

He and Wood made the most of every scoring opportunity against bowling which occasionally allowed them too much width, and Wood pulled sixes off Moss and Graeme Welch on his way to his eighth 50 in ten consecutive championship innings. He had faced 97 balls and struck six fours.

Paget was given his first bowl at 105 for one in 37 overs and the youngster immediately showed plenty of promise with a high floating action and a good length. His first 27 deliveries cost him only five runs before McGrath drove him over mid-off for four.

Wood made his first mistake on 66 when he was put down low at first slip by Welch off Mo Sheikh but the second-wicket pair continued to prosper and McGrath's 50 came from 66 balls with the century stand arriving soon afterwards in 25 overs.

The weather was closing in rapidly and Wood just had time to scamper the single that brought him his 15th first-class century for Yorkshire.
