LOS ANGELES — Rob Segedin set a Dodgers record with four RBI in his major league debut, Adrian Gonzalez hit his 300th career home run and Los Angeles beat the Boston Red Sox 8-5 on Sunday night.

With the bases loaded and one out in the fourth, Segedin drilled a 2-0 pitch from David Price (9-8) over the head of center fielder Mookie Betts for a two-run double, his first big league hit in his second at-bat.

Segedin came up again with two outs in the fifth and the bases loaded, and he lined a single to right to give the Dodgers a 6-2 lead. He was lifted in a sixth-inning double switch.

Jesse Chavez (1-0) got the win with 11/3 innings in relief. Kenley Jansen struck out the side in the ninth to earn his 34th save.

Howie Kendrick and Justin Turner added a solo homer each for Los Angeles.
