Dodgers pitcher Clayton Kershaw will make the first rehabilitation start of his career Friday for Single-A Rancho Cucamonga.No timetable has been set for his return to a major-league mound, but manager Don Mattingly said Wednesday that Kershaw will need at least two rehab starts total. He's expected to throw approximately 55 pitches, not much more than he threw in a three-inning simulated game Sunday at Dodger Stadium.
