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. 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. 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.
