"It's between those two, but we have to see if we need them tonight," Washington said before Monday's game.
Lindblom is 0-2 with a 5.40 ERA in four starts for the Rangers and hasn't allowed a run in three relief appearances. But he was also 7-0 with a 1.99 ERA in 10 starts and one relief appearance for Triple-A Round Rock after being switched from the bullpen to the rotation at the beginning of the season.
"My preference is I'd like to start but you can't complain about being in the big leagues in any capacity," Lindblom said. "Whether it's in the rotation or in the bullpen, doesn't matter."
Wolf pitched a third of an inning on Monday night, but after the Rangers' 8-5 victory, Washington still held off making a formal announcement on a starter for Wednesday. Washington said he wanted to discuss it with pitching coach Mike Maddux before making a call.
