Potts returned second-innings figures of 7 for 40, and match figures of 11 for 101, as Glamorgan were bowled out for 137 in pursuit of 196 to win at Chester-le-Street
Durham (day four of four): Durham 311 & 249, Glamorgan 365 & 137 - Durham won by 58 runs
Matthew Potts enhanced his England credentials by claiming career-best figures to inspire Durham to a dramatic 58-run victory over Glamorgan on the final day of their LV= Insurance County Championship Division Two clash at the Riverside.
Potts was in breathtaking form and took five wickets on final day, having previously claimed two in the evening session of day three, ending the innings with figures 7 for 40 and match figures of 11 for 101.
Glamorgan were to rue a collapse from 65 for 2 to 137 all out in pursuit of their victory target that began when Marnus Labuschagne was out from the penultimate ball of day three.
The Welsh side were penalised five penalty runs for a level two offence.
Once Potts made inroads in the early overs of the final morning, the momentum was truly with the home side. The England hopeful blew away their resistance that should surely put him on the path to be included in teammate Ben Stokes' first squad as captain. More importantly for Durham, it ended a run of five matches without a win in the County Championship to propel them up into third place in Division Two.
Durham required a fast start to put the pressure on the visitors. Potts answered the call for his team, producing a vicious bouncer that caught the glove of Kiran Carlson. Carlson was not thrilled with the decision, but Alex Wharf raised the finger.

Potts then prised out Sam Northeast, who had looked comfortable at the crease. Scott Borthwick initially spilled the catch, but managed to clamp his legs together to claim the ball at the second attempt to send Northeast on his way for 26.
Potts made way after his initial burst, but Brydon Carse ensured that the intensity from the hosts did not wane. He bowled with pace and accuracy after struggling in the first innings. An array of short-pitch bowling ended Billy Root's stay at the crease for 10 as he gloved one behind, attempting a hook shot that had previously brought him a boundary earlier in the over.
Sensing another opportunity Borthwick brought Potts back into the attack for a short spell. The 23-year-old claimed his fourth five-wicket haul of the season when pinned Glamorgan skipper David Lloyd lbw, who was batting at No.8 after suffering an injury on day three.
Carse turned the momentum firmly in the favour of the home side when he found Chris Cooke's outside edge before lunch, removing the last recognised Glamorgan batter.
Potts sensed blood in the water after lunch, and he drove his side over the line by dismissing Michael Neser with a brilliant yorker that caught the toe of the Aussie before clean bowling Michael Hogan to wrap up the victory, sparking massive celebrations from the hosts in the middle.
