LOS ANGELES -- The Los Angeles Dodgers still don't have a timetable for ace Clayton Kershaw to return to their rotation or even go out on a rehab assignment, but he is getting closer.Kershaw will throw to hitters Sunday for the first time since he pitched the season opener March 22 in Australia. The left-hander went on the disabled list because of inflammation in his back after that start, but he is scheduled to throw another bullpen and then throw about 15 pitches to hitters before the Dodgers' finale against the Arizona Diamondbacks.
