OAKLAND -- The Rangers have activated Alexi Ogando off the disabled list but are not ready to do the same with fellow right-handed reliever Koji Uehara.
Uehara still has some tightness in the lat muscle in his right rib cage and is going to need more time on the disabled list. He has been sidelined since June 10 and pitched a scoreless inning on Saturday night for Triple-A Round Rock. That was his first and only appearance on medical rehabilitation assignment.
Ogando replaces catcher Yorvit Torrealba, who was placed on paternity leave and will miss the Rangers two-game series with the Athletics. He is expected to be back on Friday when the Rangers open a three-game series against the Angels. Mike Napoli, who missed two games in Seattle with a bruise on his right leg, went through agility drills on Tuesday and is expected to return to the lineup.
Ogando strained his right groin muscle running the bases in a game against the Giants on June 10. He is 1-0 with a 2.08 ERA in 28 games on the season and pitched three scoreless innings in two rehab assignments for Round Rock.
