Major League veteran Ramiro Mendoza tossed six scoreless innings as Columbus edged visiting Buffalo, 3-2, on Tuesday.
Mendoza (2-1) allowed two hits, struck out four and walked two while lowering his ERA to 1.32. In six appearances, the right-hander has yielded four earned runs while striking out 22 and walking four over 27 1/3 innings.
Jose Veras allowed one run on one hit in the ninth before nailing down his fifth save. Robert Stratton and Jason Conti hit solo homers for Columbus (22-29), which snapped a two-game skid.
Jason Cooper got Buffalo (27-27) on the board with an RBI double in the eighth, but the Clippers answered in the bottom of the frame. Kevin Thompson walked with one out, stole second, moved to third on Kevin Reese's groundout and scored on a wild pitch by reliever Andrew Brown.
Hyang-Nam Choi (2-3) took the loss after allowing two runs on three hits over 5 2/3 innings. He struck out five and walked one.
Buffalo manager Torey Lovullo was ejected in the fifth for arguing a balk call against Choi.
