SAN DIEGO -- Brandon Morrow pitched seven strong innings to earn his first win with San Diego and Alexi Amarista and Derek Norris homered as the Padres beat the NL-West leading Dodgers 3-1 Sunday to snap a four-game losing streak.
A night after the Padres allowed four home runs, Morrow gave up only one longball, a leadoff shot in the fifth by rookie Alex Guerrero. The rookie has five homers and 13 RBIs since making his season debut on April 11.
Morrow (1-0), signed as a free agent in December, held the Dodgers to one run and five hits while striking out four and walking one. He had no-decisions in his first three starts.
Adrian Gonzalez, who hit a three-run shot in Saturday night's 11-8 Dodgers win for his sixth homer against the Padres this season, didn't hit a ball out of the infield in going 0 for 3 against Morrow.
The teams combined to hit 10 homers in two games and 11 in the series.
Scott Baker (0-1) lost his Dodgers debut after they selected his contract from Triple-A Oklahoma City. He signed with the club on April 5 after being released by the New York Yankees at the end of spring training.
Baker gave up three runs and four hits in seven innings.
The 5-foot-6, 159-pound Amarista drove a 3-2 pitch from Baker an estimated 398 feet into the seats in right field leading off the third, his first. It came on the 10th pitch of the at-bat.
Norris, acquired from Oakland during San Diego's December roster revamp, homered to left with one out in the seventh, his first with the Padres. Norris also had an RBI single in the fourth.
Norris threw out Jimmy Rollins trying to steal second in the first. He's thrown out eight baserunners compared to only 12 last season.
San Diego's Yangervis Solarte was thrown out trying to score from first on Matt Kemp's double to center field in the first inning. He slid head-first and appeared to injure his left wrist but he stayed in the game.
