Triallist Chris Sanders and Mahaaz Ahmed both picked up three wickets as Worcestershire Seconds claimed maximum bowling points on the opening day of the Championship match with Yorkshire at Kidderminster.
Right arm seamer Sanders, who is affiliated to Lancashire CCC and attends Loughborough University, finished with 3-53 from 14 overs and Ahmed 3-66 from 24 overs.
They were largely responsible in Yorkshire being bowled out for 282 in 83 overs as Worcestershire secured four points to their opponents three at Chester Road.
Worcestershire paceman Adam Finch made an early breakthrough when Finlay Bean (11) was caught behind by keeper and captain Alex Milton.
Former Worcestershire Academy player Will Fraine (52) and Arjun Ramkumar (37) added 59 before both fell to Sanders – at mid wicket and mid on respectively.
Jordan Thompson made a run a ball 53 with nine fours until he was caught in the covers off Brinder Phagura (14-3-53-2).
But wickets went down at regular intervals – one of them to another triallist in ex Middlesex right arm seamer and former England Under-19 player Arthur Godsal who has been playing Minor Counties cricket for Wiltshire.
Yorkshire were 207-8 at one stage but eked out 75 runs from the last two wickets thanks to useful contributions from Josh Shaw (37), Josh Poysden (21 not out) and Jared Warner (20).
When Worcestershire replied, Ollie Westbury (18) and Angus Robson (15) were both dismissed by Warner and they closed on 38-2 from 19 overs.
