"But the blister changed things," Washington said.
Ogando said he has a fake nail on the finger to help protect the blister and has not thrown a bullpen session with the nail on. Washington said he wasn't sure if Ogando would pitch Sunday, and the club was concerned enough that it sent third catcher Taylor Teagarden to Triple-A Round Rock in order to activate closer Neftali Feliz off the disabled list.
If the Rangers skip Ogando, they could allow the blister to heal through this homestand because of Thursday's off day and have him pitch May 17 in Chicago.
