COUNTY CHAMPIONSHIP DIVISION TWO, New Road:
Worcestershire 308 & 319 beat Surrey 259 & 130 by 238 runs
Worcs 22pts, Surrey 5pts
Shakib Al Hasan is the first Bangladeshi to play county cricket
Surrey collapsed on the final morning to slip to a 238-run defeat by Worcestershire at New Road.
Resuming on 66-4, needing 369 to win, Rory Hamilton-Brown and Steven Davies added 51 for the fifth wicket.
But when they both fell to former Bangladesh captain Shakib Al Hasan (6-42) inside three balls, it signalled the beginning of the Surrey demise.
Matt Mason then picked up three victims as Surrey lost their last six wickets for 18 runs to be bowled out for 130.
The win leaves Worcestershire with a realistic chance of promotion from Division Two, as they climb to fourth in the table, 18 points behind second-placed Glamorgan.
Hamilton-Brown and Davies tried to take the attack to the hosts - at one point six fours and two sixes came in a 13-ball spell - but both fell in the space of three Shakib deliveries.
Worcestershire old boy Davies was caught at mid-off and then Hamilton-Brown was well taken by James Cameron at deep extra cover.
Paceman Mason then removed Matthew Spriegel, Gareth Batty and Stewart Walters in the space of seven balls.
Batty, the other Worcestershire old boy in the Surrey team, was involved in an exchange with a member of the crowd after his dismissal.
Back on the pitch, Shakib then trapped Chris Tremlett lbw - the sixth and final Surrey wicket to fall just 48 minutes into the day - to complete his best figures in the County Championship.
Worcestershire say no action will be taken following an incident after Surrey all-rounder Batty was out.
He appeared to confront two spectators in the pavilion, and after removing his pads went to talk to a spectator in the New Road stand who had shouted a remark when he was out for six.
The former England spinner was eventually led away by Surrey coach Ian Salisbury.
Worcestershire chief executive Mark Newton says they have spoken to Batty and the spectator and as far as they are concerned the incident is closed.
Worcestershire director of cricket Steve Rhodes told BBC Hereford & Worcester:
"I am delighted with the four days. It has been a testing season in many ways with the development of young players.
"I am very pleased for Daryl [Mitchell] in his first game as captain, he a good tune out of the boys.
"There were some important partnerships, James Cameron with David Wheeldon in that first innings when they got us out of jail, Alexei [Kervezee] in the second innings and some very good bowling along the way.
"Surrey are one of the better teams you want to beat, they are the biggest club in county cricket.
"They have the biggest wallet in county cricket, they spend a lot of money and this is one instance I tend to like when we send them home with nothing."
