India discard Zaheer Khan produced yet another incisive spell of fast bowling to provide Worcestershire with a terrific start against Somerset in a County Championship Division Two cricket match at Worcester county ground on Wednesday.

The left arm seamer dismissed England vice-captain Marcus Trescothick for a 15-ball duck as Worcestershire made early inroads into Somerset, who were struggling at 237 for six at tea on the opening day.

Zaheer, who starred with 3 for 26 in Worcestershire's C and G Trophy victory over Nottinghamshire two days ago, then returned to effect the second breakthrough by accounting for 24-year old wicketkeeper-batsman Carl Gazzard (22).

Gazzard had added 67-runs for the sixth wicket with Wesley Durston (50 no) to lift Somerset from 168 for five before Zaheer had the right-handed batsman leg before wicket for figures of 16-7-41-2.

England international Kabir Ali (1-65), Western Australian paceman Matt Mason (1-41) and 22-year old quick Nadeem Malik (2-58) shared the rest of the spoils.
