Manager Ron Washington said the Rangers may push up Darvish after Tuesday's start. The Rangers are off next Thursday as well and Darvish may pitch on four days' rest so he can face the Angels on Sunday night in Anaheim.
"It just depends on his workload," Washington said.
Darvish has become more economical with his pitches. He is averaging 15.1 pitches per inning this season, down from 16.5 in each of the past two years.
"He has held up well," Washington said. "He really hasn't exerted himself. I don't think he exerted himself the other night. Except for the first few innings, I thought he breezed."
