Jack Shantry and Matt Henry ensured Worcestershire claimed maximum bowling points as Gloucestershire lost five quick wickets on the second day of the Specsavers County Championship match at Bristol.
Gloucestersire resumed on 336-5 from 96 overs and were eventually dismissed for 380 in 114.2 overs.
Shantry finished with 4-89 from 31.2 overs and Henry, on his County debut, 3-89 from 31 overs as the pair bowled unchanged for 75 minutes this morning.
The initial breakthrough came in the first over from Shantry as Kieran Noema-Barnett failed to add to his overnight 84 before pulling a short delivery into the hands of Ross Whiteley on the square leg boundary.
Whiteley claimed his fourth catch of the innings, this time at third slip, as Jack Taylor (12) edged a delivery from Henry.
Liam Norwell (9) was then trapped lbw by Shantry and then Henry accounted for century-maker and New Zealand compatriot Hamish Marshall to secure a third bowling point in the 108th over.
Marshall on 135 went to hook a bouncer and only top-edged through to keeper Ben Cox who held onto a fine catch. He struck 15 fours in his 223 ball innings.
Shantry wrapped up the innings when David Payne (2) was bowled via the inside edge.
Worcestershire suffered an early setback when they began their reply with skipper Daryl Mitchell lbw to Payne for nought from the first ball of the innings.
Moeen Ali looked in good touch and struck two boundaries in the same over from Payne.
By lunch Moeen (19*) and Brett D'Oliveira (17*) had taken Worcestershire to 40-1 from 10 overs.
