Shields, who allowed a two-run homer to Alex Guerrero in a three-run seventh inning, became the first Padres starting pitcher to begin a season with a 6-0 mark since Andy Hawkins went 11-0 to begin the 1985 season.
MOMENTS THAT MATTERED
Trouble comes early: In six previous starts this season (Major and Minor Leagues) Frias hadn't allowed four runs in a game, but he was four runs down after four hitters in this game because of Upton's slam. It was the second home run he's allowed this season. Through two innings Frias had allowed eight runs, one more than he allowed in his other six Dodgers games this year.
