But the Padres, who trailed 6-1 at one point, didn't go quietly. They got two home runs from Hedges -- a two-run home run in the second inning and a three-run shot in the sixth inning. Hedges also threw out Segura twice on stolen-base attempts.
"I'm a fan of two home runs, it's not hard to like that," said Padres manager Andy Green. "He's been working really hard, and I think you're starting to see some of that pay off right now. He's done a great job with [hitting coach] Alan Zinter."
Peter O'Brien, trying to win a job on the D-backs' bench, drilled a two-run homer as part of a six-run second inning against San Diego starter Brandon Maurer. Jake Lamb also went deep for Arizona.
Maurer, who starred in relief last season but is being moved to the rotation, got one out in the second inning before reaching his pitch limit. He allowed five runs on two hits with three walks in 1 1/3 innings.
Arizona pitcher Zack Godley allowed three runs (one earned) on three hits over three innings. He had two strikeouts. Godley is in contention for the No. 5 spot in the rotation.
Cory Spangenberg, Jon Jay and Yangervis Solarte each had two hits for the Padres.
