Weather may dictate Dodgers rotation this weekend

With rain in the forecast Friday in San Francisco, the Dodgers have held off finalizing their starting pitchers for this weekend’s series against the Giants.

Clayton Kershaw will start Sunday afternoon, with Kenta Maeda listed for Friday and a remaining spot to be filled for Saturday.

Maeda was available from the bullpen Wednesday, but manager Dave Roberts did not use him in a 3-0 loss to Arizona. If the game Friday is postponed, Roberts will choose between Maeda, Rich Hill and Hyun-Jin Ryu for Saturday.

The team could use Maeda in the bullpen against San Francisco and skip Ryu if the rain forces a two-game series.

“If there is a rainout, then we have to pivot and figure out who we want to throw,” Roberts said. “There’s some moving parts. We really don’t have a lot of clarity.”

If Friday gets washed out, Roberts does not believe the teams would play a doubleheader Saturday or Sunday. The Dodgers make two more trips to San Francisco and the Giants start another series Monday.

Kershaw is locked into Sunday because the Dodgers have next Monday off, and want to keep Kershaw on his regular schedule.

“We want to make sure that Clayton pitches,” Roberts said.

Turner, Koehler remain in Arizona

Justin Turner (fractured wrist) and Tom Koehler (shoulder strain) accompanied the Dodgers to Chase Field. They are not scheduled to make the trip to San Francisco. The duo will transition their rehab to the club’s Arizona spring training site.

Turner is scheduled to start swinging a bat next week, Roberts said. There is still no timetable for Koehler’s return.

Urias update

Julio Urias (anterior capsule surgery) recently had his tonsils removed, which delayed his throwing program, Roberts said. Urias, 21,has not been cleared to pitch from a mound.

“He is tracking in the right direction,” Roberts said. “Body great. Shoulder great. So he’s in a good place, and he’ll resume throwing sometime next week.”
