The Big River, Rio Ruiz takes on Clayton Kershaw and Rancho Cucamonga tonight Posted on April 25, 2014 by Fred Robledo 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 Dodgers manager Don Mattingly confirmed that Kershaw will need at least two rehab starts total. He’s expected to throw approximately 55 pitches Friday against the Lancaster Jethawks, who feature former Bishop Amat star and Tribune player of the year Rio Ruiz. Kershaw threw a three-inning simulated game Sunday at Dodger Stadium. “He came out of the bullpen good yesterday and we feel like we’re ready,” Mattingly said. “I don’t think anyone’s going to let him go out, even throw that sim game, if we weren’t allowing him just to go pitch.” Kershaw hasn’t any setbacks in his recovery from a strained teres major muscle in his upper left back since he first threw off a mound 10 days ago.
