Rangers starter Yu Darvish will begin a rehab assignment with Double-A Frisco, Jeff Wilson of the Fort Worth Star-Telegram reports. He’ll throw two innings or 30 pitches, whichever threshold he meets first.

Darvish, 29, has been out since August 2014 after undergoing Tommy John surgery on his right elbow. Lately, he’s been throwing bullpens and batting practice, and the Rangers feel confident enough to send him out on a rehab assignment. If all goes well, Darvish could rejoin the rotation, currently led by Cole Hamels, by the end of May.

Darvish has two years and $21 million remaining on his contract with the Rangers.
