ARLINGTON -- Craig Gentry made his return to the Rangers' clubhouse before Wednesday's game against the Mariners, and on Thursday he was activated from the disabled list.
Five members of the Rangers' bullpen combined to pitch 6 1/3 innings in Tuesday's loss, and Gentry was kept off the roster to allow the pitching staff more flexibility during Wednesday's 4-3 loss to Seattle.
But now that the series with the Mariners is complete and the Rangers are preparing to open a series in Oakland on Friday, the timing was right to make the move on Thursday.
Relief pitcher Darren O'Day was optioned to Triple-A Round Rock to make room for Gentry, and the holding pattern that Gentry had been in for the last five days came to an end.
"I thought I was coming back on Sunday, and they called and said, 'Stay for a couple of days,'" Gentry said on Wednesday. "I don't know why, but it was probably good to get a few more at-bats down there so I could feel more comfortable down there and come back here and not miss a beat."
Gentry has had no recurring headaches or any other symptoms in the aftermath of his concussion.
"I felt great, went out there and played every single game, and there were no issues whatsoever," he said.
At the time of his injury, Gentry had been platooning at center field with Endy Chavez, batting .265 in 83 at-bats.
