PHOENIX (AP) Corey Seager had four hits, including his first career homer, as the Los Angeles Dodgers went deep four times in a 9-5 victory over the Arizona Diamondbacks on Saturday night.

Joc Pederson, Adrian Gonzalez and Carl Crawford also homered for the NL West-leading Dodgers.

Seager, playing shortstop with veteran Jimmy Rollins only available for pinch-running duty because of injured finger, had three RBIs, scored three times and stole a base. He got help from a Diamondbacks fan who reached over the padding down the left-field line in the fifth inning to take a seemingly catchable foul ball away from David Peralta and Jake Lamb, and Seager then homered to right in the same at-bat.

J.P. Howell (6-1), the first of seven Dodgers relievers, got the last out in Arizona's three-run fourth to pick up the win.

Rubby De La Rosa (12-8) gave up six runs and nine hits in two-plus innings to fall to 0-3 against the Dodgers this season

Crawford began the game with his ninth career leadoff home run, a line drive just over the right-field fence. Then Chase Utley singled, took third on a two-out single by Andre Ethier and scored on a soft ground ball to second base from Seager that the Diamondbacks' Chris Owings juggled for a hit.

That gave the Dodgers a 2-0 lead in the first inning, and they went ahead 7-0 in the third on Gonzalez's leadoff home run, Ethier's run-scoring double, and RBI single for Seager and Pederson's two-run blast.

The Diamondbacks rallied for three runs in the bottom of the fourth and loaded the bases with two out, after Pete O'Brien's pinch RBI single and sacrifice flies for Nick Ahmed and Ender Inciarte.

Mike Bolsinger had thrown a wild pitch earlier in the inning to put runners in scoring position. He was replaced by Howell after an intentional walk to Paul Goldschmidt, and Howell got David Peralta to fly out to shallow left field to end the threat.

Seager made it 8-3 with his home run, and Inciarte cut the lead to 8-4 in the sixth with a single to drive in A.J. Pollock.

Peralta's 15th home run of the season, off the Dodgers' Luis Avilan, came in the seventh and Alex Guerrero added an RBI double in the ninth.

De La Rosa brushed back Seager with an inside pitch in the third, just before Seager singled up the middle. Both teams were warned by home plate umpire Brian O'Nora.

UMPIRING CHANGE

O'Nora joined the umpiring crew for the series in time for Saturday's game and worked home plate, with Jim Wolf out after being struck in the mask by a foul ball during the second inning on Friday night.
