Mattingly remains mum on Kershaw's return date

LOS ANGELES -- Clayton Kershaw will make a Minor League rehab start for Class A Advanced Rancho Cucamonga on Friday night.

Manager Don Mattingly would not say how soon Kershaw might return to the Dodgers' rotation, but neither would Mattingly confirm who would start for him next week in Minneapolis, where the Dodgers open a three-city trip.

Kershaw has been on the disabled list since suffering a strained teres major muscle on the left side of his back in his Opening Night win in Australia. It is Kershaw's first time on the disabled list.

On Wednesday, Mattingly said Kershaw would need at least a second rehab start before being activated. Kershaw will probably lobby to return immediately if Friday night goes well. He is expected to make 55-65 pitches and his next day to pitch would be Wednesday. The Dodgers have a travel day on Monday.

Kershaw's spot in the rotation has been filled by Paul Maholm, who is scheduled to pitch Saturday and again next Friday.
