The run production made a winner of one-time Rockies lefty Drew Pomeranz (1-0), who struck out seven and gave up two runs in five innings. The Padres' Wil Myers added a solo shot to center off Chad Qualls in the ninth.
The crowd of 35,177 also witnessed the first Major League game in which Rockies rookie shortstop Trevor Story did not homer. His homers in the first four games tied him with Willie Mays (1971), Mark McGwire (1998), Nelson Cruz (2011) and Chris Davis (2013) for longest such streak to begin a season.
