The Orioles received Minor League catcher David Freitas from the A's on Thursday, completing the Dec. 2 deal that sent closer Jim Johnson to Oakland for second baseman Jemile Weeks.
The 24-year-old Freitas hit .231 with 14 doubles, seven home runs and 30 RBIs in 90 games for Oakland's Triple-A and Double-A affiliates last season.
Freitas, a right-handed hitter, was originally selected in the 15th round of the 2010 First-Year Player Draft by the Nationals. He is a .276 career Minor League hitter in four seasons.
