The Los Angeles Angels promoted their top prospect, second baseman Christian Moore, ahead of Friday's game in Baltimore.
He hit ninth and played second base in his debut for the Angels.
Moore, 22, was promoted to Triple-A in mid-May and did well enough to join the Angels, whose offense is 13th in runs scored in the American League. He batted .279 with five home runs, 32 RBIs and a .796 OPS combined at Double-A Rocket City and Triple-A Salt Lake this season.
His rapid ascent through the Angels' farm system follows a trend under general manager Perry Minasian, who previously promoted shortstop Zach Neto (48 minor league games) and first baseman Nolan Schanuel (21 games) early in their pro careers. Moore is ranked the fourth-best prospect in the Angels' system, according to ESPN's Kiley McDaniel.
A Brooklyn, New York, native, Moore hit a Tennessee-record 34 home runs in 72 games last year in helping to power the Vols to their first Men's College World Series title.
