Kershaw, Wilson, Billingsley all improving

PHOENIX -- Dodgers pitchers Clayton Kershaw, Brian Wilson and Chad Billingsley, who are all on the 15-day disabled list, continued their recoveries from injuries Friday, but manager Don Mattingly said there isn't a return date set for any of them.

Kershaw was given a light day after significant progress earlier in the week from a strained Teres Major muscle under his left armpit.

Wilson, rebuilding arm strength after a short Spring Training, will pitch in a game Saturday at the club's Camelback Ranch-Glendale complex.

Billingsley reported no further discomfort after a scar tissue episode in a Minor League rehab assignment, but there is no date set for him to resume game action as he returns from Tommy John surgery.
