Yu Darvish surrendered four earned runs in eight innings but the Rangers topped the Astros 8-7 on Saturday. Darvish had some control issues, yielding three walks against a Houston lineup that is not known for its plate discipline. But the right-hander struck out nine and limited the Astros to four hits while moving to 6-1 on the season. He will carry a brilliant 2.73 ERA and 0.91 WHIP into his next scheduled start against the Tigers.
