TRENTON, N.J. — Danny Oh scored the go-ahead run on a groundout in the sixth inning, and the Trenton Thunder snapped the Portland Sea Dogs’ four-game winning streak with a 3-2 victory Monday night at Arm & Hammer Park.

Oh led off the bottom of the sixth with a walk against reliever Mike Augliera (2-14), then stole second, took third on a groundout and scored his third run of the game on another groundout by Eddy Rodriguez.

Augliera took the loss despite throwing three hitless innings in relief of Danny Rosenbaum, who allowed 10 hits and two runs in four innings. He tied the franchise record for losses in one season, set by Mark Johnson in 1998.

Jaron Long (2-2) worked three scoreless innings in relief for Trenton (55-47) to earn the victory. Former Red Sox reliever Andrew Bailey pitched a perfect ninth for his second save.

The Sea Dogs (39-64) took a 1-0 lead in the second inning. Mike Miller led off with a single, stole second with one out and scored on Keury De La Cruz’s two-out single off Kyle Haynes.

Trenton answered quickly in the bottom of the second. After a hit by Oh and an error but two runners on with nobody out, Rosenbaum got Rodriguez to ground into a double play. But Juan Graterol followed with an RBI single.

The Thunder went ahead 2-1 in the fourth on consecutive singles by Oh, Dan Fiorito and Rodriguez. An unassisted double play on a line drive to first baseman Sam Travis helped Rosenbaum avoid further damage.

The Sea Dogs then tied the game in the fifth inning on three straight two-out singles, by Carlos Asuaje, Travis and Tim Roberson.
