FRISCO, Texas (AP) Yu Darvish threw six scoreless innings Sunday in what is likely to be his last rehab start before returning to the Texas Rangers rotation for the first time since late in the 2014 season.

Darvish is coming back from Tommy John surgery and threw 56 of 87 pitches for strikes while pitching for Double-A Frisco. He allowed three hits and walked one against San Antonio, an affiliate of the San Diego Padres.

The right-hander from Japan last pitched in a major league game Aug. 9, 2014, before dealing with right elbow inflammation. He had more issues the following spring and had surgery on March 17, 2015.
