Manager Ron Washington said that is one of the reasons the Rangers adjusted their rotation. The Rangers are off on Monday and that would give the bullpen a chance to recover if Martinez has a short outing on Sunday.
The switch also means that Lewis will likely have to pitch against the Nationals later this month. Washington originally had Lewis missing that series so he wouldn't have to hit in the National League park. He'll likely end up pitching there unless weather problems dictate otherwise.
"I might tell him not to take the bat off his shoulder," Washington said. "I'll make him bunt every chance I get."
