Teagarden, who turns 28 on December 21, has appeared in 118 games for Texas over the last four seasons, batting .220 (77-350) with 16 home runs and 49 RBI. He has a .985 career fielding percentage in the major leagues and has thrown out 30.5 percent of runners attempting to steal (25-82).
“Taylor is an accomplished catcher who has shown an ability to handle a pitching staff and control the running game,” said Orioles Executive Vice President of Baseball Operations DAN DUQUETTE. “We believe he will be a nice complement to Matt Wieters and our pitching staff and offensively he will provide good power.”
In 14 games for Texas in 2011, Teagarden batted .235 (8-34) and in 42 games for Triple-A Round Rock, he batted .285 (43-151) with 12 home runs and 22 RBI.
Teagarden was the Rangers' third round pick in the 2005 First Year Player Draft out of the University of Texas, where he led the Longhorns to the 2005 National Championship.
Henry, 21, appeared in 29 games between Class-A Delmarva (20 games) and Class-A Frederick (nine games) in 2011, going 4-3 with a 2.22 ERA (52.2IP, 13ER).
Henry was the Orioles' fourth round selection in the 2009 First Year Player Draft out of South Mountain (AZ) Junior College.
To clear room for Teagarden on the 40-man roster, LHP Pedro Viola has been designated for assignment.
