GENEVA — Just one run in the bottom of the seventh inning was all the Geneva Red Wings needed to down the Jamestown Jammers for the second game in a row, 1-0, Wednesday night in a Perfect Game Collegiate Baseball League matchup.

Matt Chamberlain delivered a run-scoring single to account for the game’s only run and help lead Geneva (11-6) to the tightly contested victory.

Slater O’Brien turned in a gem on the hill for the Red Wings, tossing seven shutout innings, only giving up two hits and striking out three. Ben Terwillinger fired the final two innings to record the six-out save.

Jake Evans, Matt Smith and Justin Etts all contributed two hits apiece in the win for Geneva.

Collin Stack (University of Maryland-Baltimore County), Jimmy Standohar (Mercyhurst University) and Connor Rule (Kansas State) picked up Jamestown’s (11-4) three hits.

It appeared as if the Jammers found a way on the board in the sixth, when Chris Estrada (University of Texas at San Antonio) launched an apparent sacrifice fly, scoring Stack. However, Stack was ruled out after it was deemed he left third base early, negating the run.

Nate Grant (St. Bonaventure University) pitched well in defeat, hurling six scoreless innings and only surrendering six hits. Colin Johnston (Monroe Community College) tossed the final two frames out of the bullpen.

The Jammers will be in action tonight back at Diethrick Park against the Newark Pilots. First pitch is slated for 7:05 p.m.
