Orioles minor league outfielder Mike Yastrzemski was promoted to Double-A Bowie on Wednesday, Single-A Frederick announced, making him the club's first 2013 draft pick to reach that level.
Yastrzemski, who is the grandson of Boston Red Sox Hall of Famer Carl Yastrzemski, hit .312/.364/.462 with a home run and 19 RBIs in 23 games for the Keys, highlighted by a cycle on July 5 against Lynchburg.
He was promoted to the Keys on June 19, after earning a South Atlantic League All-Star nod with a .306/.365/.554 batting line for Low-A Delmarva.
Yastrzemski reached double-digits in doubles (14), triples (10), home runs (10) and steals (12) in the South Atlantic League, the only player in the league to reach each of those plateaus despite not having played in that league for nearly a month.
Outfielder Lucas Herbst will take Yastrzemski's spot with Frederick.
Yastrzemski will join Bowie after the Double-A All-Star break. Several other roster moves, including promotions for Baysox outfielder Dariel Alvarez and first baseman Christian Walker, are expected before the second half resumes in Double-A and Triple-A.
