Mike Colla posted a career-high eight strikeouts and Richie Shaffer homered to lead the Biscuits in a 3-2 rain-shortened win at Pensacola on Thursday.
Colla worked seven innings, the most by a Biscuits starter this year, and gave up two runs on seven hits. He walked one.
Colla also recorded the first quality start for Montgomery this season.
The game was stopped by heavy rain with no outs in the top of the ninth inning.
Shaffer homered to lead off the second inning for the game's first run. Shaffer has a Biscuits-best three home runs.
Montgomery made it 3-0 in the fourth on a two-run Luke Maile single. After Cameron Seitzer's one-out single, Alejandro Segovia drew a two-out walk and Jeff Malm singled to bring up Maile.
The Blue Wahoos hit Colla for two runs on three hits in the fourth. Steve Selsky hit a two-run single with two outs.
Colla, a seventh-year pro, struck out seven in four previous appearances for an affiliated team, most recently for Double-A Altoona on April 29, 2012.
