Skipper Paul Collingwood fell three short of a century as Durham established a first innings lead of 116 on the third day of the Specsavers County Championship match with Gloucestershire at Bristol.
Resuming on 270 for four, the visitors were dismissed for 419, with Collingwood the last man out for 97, made from 178 balls, with 10 fours. Michael Richardson hit 57 and shared a fifth-wicket stand of 122 in 42 overs with his captain. Craig Miles was the most successful Gloucestershire bowler with five for 99 from 28 overs.
By the close the hosts had fought back well, reaching 175 for three in their second innings and led by 59, Chris Dent and Will Tavare making their second half-centuries of the match.
Collingwood batted comfortably through the morning session. Resuming on 28, the veteran former England all-rounder was unbeaten on 78 at lunch, with his side 372 for seven and 69 in front. He reached his half-century off 112 balls, with 5 fours, shortly after Richardson had got to the same landmark from 130 deliveries, hitting four boundaries.
Miles then had Richardson caught behind pulling and followed up by knocking back Stuart Poynter’s off-stump when he had made nine in a seven-over spell of two for 26.
Brydon Carse was caught behind off Liam Norwell for seven, the seamer’s 19th wicket of the season, in a morning session extended by 15 minutes to make up for time lost on the opening day.
The afternoon saw Mark Wood, on 13, top-edge a pull shot off David Payne to give a simple catch to Chris Liddle at mid-on before Graham Onions became Miles’ fifth victim, caught at cover for ten attempting to force a short ball through the leg side and miscuing in the opposite direction..
Collingwood had faced 178 balls and hit 10 fours when falling just short of his ton, well caught by George Hankins at slip, who showed great anticipation to hold the chance offered by a reverse paddle off Graeme van Buuren.
The Durham skipper said: "It would have been nice to have reached three figures, but with only one wicket left I was always going to push for runs in that over.
"When you play that shot (reverse paddle) you don't expect the slip fielder to move across and anticipate where the ball is going. Now I wish I had hit it finer to where he had been standing! We bowled really well this afternoon without a great deal of reward, but we are still in a good position and hopefully we can get wickets quickly tomorrow."
Cameron Bancroft’s miserable start to his second spell with Gloucestershire continued when he played across a straight ball from Chris Rushworth and departed for 13 with their second innings score on 30.
But Dent and Tavare then batted with confidence in bright sunshine, the latter being first to his half-century, off 70 balls with 6 fours.
Tavare again looked in good form until he was undone on 55 by the third ball of the match from Cameron Steel, brought on to bowl leg-spin in what proved an inspired move by Collingwood.
Steel appeared to deceive Tavare with a googly, which tucked him up and bowled him, much to the delight of the young bowler and his team-mates.
There was a life for van Buuren when he was dropped by wicketkeeper Stuart Poynter off Carse, but on 23 he was pinned lbw by Onions with the score on 159 and Gloucestershire 43 ahead.
Dent had reached his half-century off 107 balls, with 6 fours, batting fluently without giving a chance. He was unbeaten on 64 at stumps.
Gloucestershire seamer Craig Miles said: "I am delighted to have taken five wickets on a pretty unhelpful pitch against what is basically a First Division side playing in Division Two.
"Durham have some very talented batsmen and on that surface it was a case of trying to be patient and build pressure. I still delivered a few too many loose balls for my liking, but there were some wicket-taking balls too.
