Devon's minor counties campaign ended on a disappointing note as they lost by 74 runs to Oxfordshire in Sidmouth.
Oxfordshire were bowled out for 375 in their second innings, giving Devon a target of 269 to win.
The home side's chase started badly, and they were 94-8 before Josh Bess rallied to make the score respectable.
Devon were eventually bowled out for 194, with Bess finishing on 88 not out, as left-arm spinner Luke Ryan took an impressive 5-58 for Oxfordshire.
The win caps a remarkable turnaround for Oxfordshire following their dismissal for just 76 runs in the first innings on Sunday.
Devon were only able to build a lead of 107 in their first innings, with Oxfordshire then going on to make 375 in their second innings.
We did not capitalise on the great position we had put ourselves in
"To lose a game by 74 runs when we had bowled them out for 76 in the first innings is a real kick in the teeth," said Devon skipper Neil Hancock.
"What we didn't do was press home our advantage when we batted. A lead of 107 may sound reasonable, but it wasn't enough to kill them off.
"Basically, we did not capitalise on the great position we had put ourselves in.
"The story of our season has been inconsistent batting. Josh Bess has done OK and a few of us have had decent season, but too many haven't."
