Through all that, manager Ron Washington is trying to sort out roles. Right-hander Phil Klein joined the Rangers on Friday, replacing left-hander Ryan Feierabend. The move leaves Cotts as the only left-hander in the bullpen. Cotts is also the Rangers' primary eighth-inning reliever. Everything else is up in the air.
"Some of these right-handers are going to have to deal with these lefties," Washington said.
Going into Friday's game, left-handed hitters were batting .182 off Roman Mendez and .236 off of Tolleson. They were 1-for-8 off Nate Adcock. Klein handled left-handers at Triple-A, allowing five singles in 29 at-bats against them.
"He could get some lefties," Washington said. "We can use him for multiple innings, probably in the middle innings. We'll see where it goes. He's moving fast, so we'll see what he has to offer."
