Darvish (elbow) is expected to make one more rehab start before rejoining the Rangers' rotation, Fort Worth Star-Telegram reports.
The right-hander made his fourth rehab start for Double-A Frisco on Tuesday, allowing three hits and one walk while striking out six over five innings (68 pitches). He typically sat in the 93-95 mph range with his fastball, but got at high as 97 mph. The tentative target date for his return to the majors is May 27, and he'd have to agree to extend his rehab assignment much beyond that with the 30-day limit expiring on June 1.
