LOS ANGELES (AP) — Prized rookie Joc Pederson hit his first career grand slam, Andre Ethier and Justin Turner added solo shots and the Los Angeles Dodgers routed the Arizona Diamondbacks, 8-0, on Friday night.

Carlos Frias (2-0) came out of the bullpen to make a spot start for Brandon McCarthy, who had season-ending Tommy John surgery on Thursday. The 25-year-old rookie struck out three and walked one over 5 1-3 sharp innings in his third big-league start.

Harmless singles by Yasmany Tomas in the second and Paul Goldschmidt in the fourth were Arizona's only hits until the sixth, when Danny Dorn pinch-hit for pitcher Rubby De La Rosa and led off with a single for his first hit in four major league at-bats.
