The D-backs sent catcher John Hester to the Orioles on Saturday to complete the December trade that brought right-handers David Hernandez and Kam Mickolio to Arizona for third baseman Mark Reynolds and a player to be named or cash. Hester, 27, has been at Triple-A Reno to start the 2011 season, batting .263 with three doubles, a home run and five RBIs in 10 games. Hester will join Triple-A Norfolk in the Orioles organization.
