The Rangers have signed right-hander Justin Miller to a minor league contract, reports Jeff Wilson of the Fort Worth Star-Telegram (Twitter link). Miller will report to Triple-A Round Rock on Monday. Miller was released by the Mariners earlier this week after he informed the team that he was going to opt out of his contract on May 1, due to a clause that gave him that right since Miller wasn't on Seattle's Major League roster by that date.
Texas has been looking for right-handed bullpen depth with Neftali Feliz on the DL and Alexi Ogando moved to the rotation. Miller had an impressive 1.04 ERA in 8 2/3 Triple A innings this season, and in 19 appearances for the Dodgers in 2010, Miller posted a 4.44 ERA and an 11.1 K/9 rate. The Rangers will be the 10th franchise Miller has pitched for during his 14-year pro career.
