JOE Clarke achieved his career-best score and Joe Leach a first century for three years as Worcestershire's batsmen dominated a rain-truncated second day against Derbyshire at New Road.

Clarke, who was unbeaten on 117 overnight, went on to make 194 as he surpassed his previous best tally of 135 against Gloucestershire at Bristol in his first innings of the summer.

Leach made an unbeaten 107 before the declaration came at 475-7 in mid-afternoon in the Specsavers County Championship Division Two encounter.

But a mixture of bad light and persistent rain meant Derbyshire faced only 2.3 overs before play was abandoned for the day.

Worcestershire had to battle hard on a sluggish pitch to reach 255-6 from 92 overs on the opening day.

But it was a different scenario on the second day as the County plundered 220 from 45 overs at nearly five runs an over.

Clarke and Leach put on 157 in 32 overs for a Worcestershire record for the seventh wicket in matches against Derbyshire.

England Lions player Clarke was eventually dismissed in the final over before lunch, caught at deep mid-wicket off Wayne Madsen aiming for the big hit which would have taken him to his double hundred.

Clarke struck one six and 25 fours in his 328-ball knock and his first full season of senior cricket has brought him five Championship hundreds and a 98.

Leach was then given good support in an unbroken eighth-wicket stand of 72 in 14 overs with Ed Barnard (32 not out).

The 25-year-old went to his hundred off 138 balls with 12 boundaries via a four through mid-wicket off Tony Palladino shortly before the declaration.

It was the first time he had reached three figures since his career-best 114 and maiden ton against Gloucestershire at Cheltenham in 2013.

Leach was batting in the top six on that occasion but since then his bowling skills have improved considerably and he is now a front-line part of the attack.

In addition to scoring nearly 600 runs batting at number eight, he is the County's leading wicket-taker in the Championship this summer with 58 victims.

Miguel Cummins took the new ball for Worcestershire fresh from his 12 wickets in the win over Sussex at Hove last week.

He should have collected another scalp with his third delivery but Ben Slater survived a chance on two off a skier at fine leg.

Only 15 balls were possible before the players left the field and then a heavy post-tea downpour ended hopes of a return to action.
