Darvish is on a six-man rotation and will pitch five innings as planned this weekend, but he'll do it Sunday morning in Surprise Stadium against some Rangers minor leaguers in an intrasquad game.
"(The Angels) are not going to show us (anything)," Rangers pitching coach Mike Maddux said. "A lot of teams do that."
Darvish pitched four innings at home against the Milwaukee Brewers on Monday and allowed one run on one hit with three walks and four strikeouts. He was pleased with his fastball command, despite needing 70 pitches in his four-inning stint.
The Rangers do not face the Angels until May 11.
That would put him in position to face the Seattle Mariners in Arlington on Monday, April 9. But Maddux said the club hasn't decided anything yet in terms of the final alignment for the opening homestand.
