The Orioles have filled their 40-man roster again, announcing Friday that they added catcher Luis Martinez on waivers from the Texas Rangers.
Martinez, 27, played in 10 games with the Rangers in 2012, getting two hits in 18 at-bats. The right-handed hitter also played in 22 games in 2011 with the San Diego Padres, the team that drafted him in the 12th round in 2007.
Martinez is now the fourth catcher on the Orioles' 40-man roster, joining starter Matt Wieters, primary backup Taylor Teagarden and Luis Exposito. Exposito and Martinez have minor league options remaining.
Orioles executive vice president Dan Duquette said he was impressed with Martinez's defense – he threw out 31 percent of basestealers in the minors – and his .362 career on-base percentage in the minor leagues.
"He has a good arm, he can get on base and he can control the running game, which are all good things," Duquette said. "I think he will be additive to the team with his defense and on-base capability. We've been looking for depth at the catching position."
Martinez is a career .272 hitter with a .362 on-base percentage in six minor league seasons in the Padres and Rangers systems. He had been designated for assignment by the Rangers last week.
