Kevin Millwood allowed one hit over five scoreless innings in a rehab start as Frisco edged visiting Tulsa, 2-1, on Sunday.
Millwood, recovering from a hamstring injury and likely to return to Texas late next week, retired the first eight batters before giving up a double to Rick Guarno in the third inning.
He retired seven of the next eight before coming out of the game. Millwood, 2-4 for the Rangers this season with a 6.62 ERA, struck out three and walked one.
Luis Mendoza (5-0) got the win in relief, striking out six over four innings -- including three in the ninth. Mendoza, who allowed two hits and a walk, started for the RoughRiders (32-17) in his previous eight outings.
Jim Fasano's home run off Drillers reliever Darren Clarke to lead off the eighth made the difference for Frisco. Jerry Hairston Jr. added a solo blast with two out in the sixth.
Clarke (1-1) took the loss, yielding one run on three hits while fanning two.
Joe Gaetti's RBI single in the sixth accounted for the Drillers' scoring.
Ryan Mattheus took the hard-luck loss for Tulsa (26-24), giving up a run on five hits and a walk with one strikeout over seven innings.
