Ethier followed a double by leadoff man Matt Kemp and a single by Hudson with his 24th home run of the season, a long drive into the right field seats. The right fielder also collected three singles and finished the day with four runs batted in.
Russell Martin singled in the fourth and with two out, Wolf hit the first Dodgers home run since 2007. Kemp then singled and Hudson hit the ball out of the park for his eighth homer and a solid 7-0 lead.
Wolf retired the first man he faced, gave up a single to XXX Roberts and then retired the next 20 Diamondbacks in a row, 10 of them by strikeout -- five in succession at one point.
Wolf added a single in the sixth and an RBI double in the eighth, then ran out of gas in the last of the eighth and gave up three hits and three runs.
Guillermo Mota closed out the eighth and the worked a 1-2-3 ninth to put the game on ice.
The win took a bit of the sting out of the game the previous night when the Dodgers lost starter Hiroki Kuroda after a line drive bounced off his head and Jonathan Broxton blew a 3-1 lead in the ninth before they lost 4-3 in 10 innings.
San Francisco lost 4-3 to the Mets and the Rockies lost 10-3 to Florida in the first game, then won the second game. Los Angeles picked up a full game on he Giants and a half-game on Colorado.

Hiroki Kuroda, who narrowly escaped frightening injury when hit on the side of the head by a line drive Saturday night, was discharged from St. Joseph's Hospital and Medical Center and is will fly home with the club
Kuroda was struck above the right ear by a line drive off the bat of pinch-hitter Rusty Ryal leading off the bottom of the sixth inning, after having held the D-backs to two hits over five scoreless innings. He never lost consciousness and there was no bleeding from the injury.
Ken Gurnick of MLB.com said Torre was under the assumption that Kuroda won't be available to make his Thursday night start against the Cubs, although Kuroda gave indications he'd be ready. Torre said Scott Elbert was scratched from his scheduled start Sunday at Albuquerque in case he's needed Thursday.
Knuckleballer Charlie Haeger, an 11-game winner for Albuquerque, draws the opening night start against the Cardinals.
