Offensive outbursts carried the Double-A Bowie Baysox and Single-A Frederick Keys to wins, but the night probably will be most remembered for Keys left-hander Brian Matusz's first victory as a member of the Orioles' minor league system.

The Triple-A Norfolk Tides lost in a low-scoring game, while the Single-A Delmarva Shorebirds allowed 11 runs in a loss to the Hagerstown Suns.

Frederick Keys (A)

Score: Frederick Keys 10, Myrtle Beach Pelicans 5 (Box score)

Recap: The Keys pounded Myrtle Beach for 10 runs and 16 hits, providing Brian Matusz (1-0) with plenty of support to earn his first victory in the organization.

The 22-year-old left-hander allowed three runs and four hits in five innings. Matusz struck out six hitters and issued three walks. He also gave up a home run to Pelicans right fielder Cody Johnson in the fourth inning.

Jason White, Tyler Henson and Chris Vinyard added two RBIs each for the Keys. Henson committed his fifth error of the season, and Billy Rowell made his first defensive miscue for Frederick.

Frederick second baseman Ryan Adams left the game in the second inning due to a slightly strained groin. The initial word from the Keys is that he could miss 7-10 days with the injury. I'll provide more updates if I hear anything.
