Yu Darvish allowed just one run over six innings but took the loss as the A's beat the Rangers on Tuesday.
Darvish allowed only a solo home run to Yoenis Cespedes on the night, but he was outdueled by Dan Straily. Even with the loss, Darvish is 7-2 with a 2.84 ERA through 10 starts. He'll hope for a better fate Monday against the Diamondbacks.
Alexi Ogando (biceps) has been playing catch but said he is only throwing around "40 percent."
"I don't know when they'll let me throw hard," the right-hander added. Ogando said that he's feeling better, so there's definitely some progress even if it might be coming slowly. There is no structural damage in Ogando's biceps, but it's unclear when he'll return.
Rangers purchased the contract of LHP Neal Cotts from Triple-A Round Rock.
Cotts hasn't appeared in the majors since 2009 but has earned a call-up with some brilliant work at Triple-A, where he's posted a 0.78 ERA and absurd 42/5 K/BB ratio over 23 innings. He'll be used in middle relief.
Ross Wolf will be recalled from Triple-A Round Rock on Wednesday to start against the A's.
Nick Tepesch has a blister on his right middle finger, so Wolf is going to take the mound in his place. Wolf has posted a promising 1.85 ERA and 25/9 K/BB ratio in 34 innings this season at the Triple-A level, but the 30-year-old right-hander is not a great fantasy streamer.
Rangers activated C A.J. Pierzynski from the 15-day disabled list.
Pierzynski went 1-for-6 with a strikeout in two rehab games with Double-A Frisco and didn't have any issues with his oblique. The 36-year-old backstop returns to a .263/.297/.411 batting line to go along with four home runs and 11 RBI in 26 games.
Making his first start for the Rangers this season, Jurickson Profar went 0-for-2 with a pair of RBI against the A's on Monday.
Profar drove in both Rangers runs with a groundout and a sac fly. Manager Ron Washington said Profar and Leury Garcia would split time at second, but as long as Profar is up, the Rangers would be crazy not to use him.
