Starting pitcher Brian Matusz was promoted to the Double-A Bowie Baysox today, according to the Orioles, and he will make his debut on Wednesday at Prince George's Stadium against the Reading Phillies.
The 22-year-old left-hander was 4-2 with a 2.16 ERA in 11 starts for the Single-A Frederick Keys so far this season. Matusz, who was the Orioles' first-round selection in the 2008 MLB draft, didn't allow a run in his final 23 innings with the Keys.
Matusz currently leads the Carolina League with 75 strikeouts, and he ranks among the league leaders with 66 2/3 innings and a 2.16 ERA. In eight of his 11 starts, Matusz struck out at least six batters.
Before his promotion, Matusz was scheduled to pitch in the California/Carolina League All-Star Game on June 23 in Lake Elsinore, Calif.
In order to make room for Matusz with the Baysox, right-hander Sean Gleason will return to the Keys.
Gleason, who won 12 games with the Single-A Delmarva Shorebirds last season, began the season with the Keys before being promoted to Bowie. He was 3-5 with a 5.96 ERA in 10 starts for the Baysox.
