Thame Town Firsts came unstuck defending a decent total at Shipton-under-Wychwood eventually losing by four wickets.
Batting first, Thame got off to a good start, and a middle-order stand of 83 between Deon Laubscher and Will Sutcliffe (33) put the visitors on course for a big score.
Laubscher racked up 90 runs before eventually being bowled out and things were looking good.
But the remaining Thame batsmen could not maintain the momentum in the face of good spin bowling from Shaun Miller, and they finished on 230 for 8.
When Shipton batted the home side exploited their ground’s small boundaries, and Jason Hunt scored 85.
Sam Lachlan (3 for 53) and Mike Higgs (3 for 58) pegged them back but the total was eventually overhauled in the penultimate over for the loss of 6 wickets.
Thame had a better result in the Bernard Tollett Cup, where they travelled to Didcot on Tuesday and won by 22 runs.
Thame scored 113 off their 18 overs, with Mike Higgs smashing 44 in 5 overs to set up an impressive win.
Didcot batted well but began to struggle against the accurate Thame bowling .
Seamer John Phippen (3 for 12) and spinner Higgs (2 for 12) were the most impressive.
Thame are now in the semi-finals and await the draw to face either Horspath, Banbury or Great Tew.
