LOS ANGELES -- Joc Pederson hit the first grand slam of his major league career and right-hander Carlos Frias threw 5 1/3 shutout innings to lead the Los Angeles Dodgers to an 8-0 rout of the Arizona Diamondbacks on Friday night in front of 50,164 at Dodger Stadium.

Right fielder Andre Ethier went 2-for-3, hit a home run and scored two runs. Third baseman Justin Turner added a home run while going 1-for-4, pinch-hitter Scott Van Slyke contributed a two-run single and Pederson finished 1-for-3.

Frias (2-0), making his first start of the season and the third of his major-league career, conceded just two hits in his first five innings. The right-hander allowed four hits and one walk in 5 1/3 innings, induced eight groundouts and struck out three.

The Dodgers took a 5-0 lead in the bottom of the second inning against right-hander Rubby De La Rosa. Third baseman Justin Turner began the inning with his second home run of the season. Los Angeles then loaded the bases when Ethier lined a single before catcher Yasmani Grandal and left fielder Alex Guerrero drew walks.

All three scored when Pederson pounded De La Rosa's first pitch halfway up the right-field bleachers. The grand slam was Pederson's first of his major league career and the Dodgers' first since outfielder Yasiel Puig hit one on June 6, 2013, against the Atlanta Braves.

After Pederson's grand slam, De La Rosa retired the next 11 batters he faced before being relieved. In five innings, De La Rosa (2-2) permitted five runs, three hits and three walks while striking out six.

Arizona had its best chance to score in the top of the sixth, loading the bases with two outs. Pinch-hitter Danny Dorn led off with a single for his first major-league hit. Center fielder A.J. Pollock followed with another single and right fielder Mark Trumbo reached base when Los Angeles shortstop Jimmy Rollins misplayed his ground ball for an error.

But right-handed reliever Pedro Baez struck out Arizona left fielder David Peralta on a 97 mph fastball to quell the threat.

In the bottom of the sixth, the Dodgers extended their lead to 6-0 on Ethier's fourth home run of the year, a solo drive halfway up the bleachers near the right-field line.

Van Slyke's pinch-single with the bases loaded in the eighth brought home two more runs. Three relievers -- Baez, right-hander Sergio Santos and left-hander J.P. Howell -- combined to permit only two base runners on a hit and an error in the final 3 2/3 innings.
