The Rangers optioned right-hander Chris Martin to Triple-A Round Rock before Tuesday's game against the Houston Astros at Globe Life Park.
The move was made to make room for first baseman Ronald Guzman, who came out of MLB's concussion protocol and was in the Rangers' lineup. Rangers manager Jeff Banister said the move had nothing to do with Martin's performance.
"We’re still nursing some guys with some minor injuries position player-wise," he said. "Chris hasn’t done anything to warrant being optioned out.Obviously, he has pitched well for us in the bullpen. It’s not necessarily the move that is optimum at this time, however you have to be able to protect some of the other players on the team too.
