The Orioles today announced that they have received catcher John Hester from the Arizona Diamondbacks to complete their December 2010 trade for third baseman Mark Reynolds. Hester has been assigned to Triple-A Norfolk. A 13th-round selection out of Stanford University by the Diamondbacks in 2006, Hester has batted .263 (10-38) in 10 games with the Triple-A Reno Aces this season. In 300 career minor league games, he has thrown out 29% of baserunners. Hester played in 53 major league games for Arizona in 2009 and 2010, batting .220 (27-123). He hit a two-run home run in his first major league at-bat on August 28, 2009 against the Houston Astros.
