Sunday is a day of rest for most people, but the Giants and Padres hope their hitters don't follow this custom. Before the Padres busted out offensively Saturday, runs had been scarce in this series, which began with a pair of 1-0 decisions.
Then again, the Giants' offense typically doesn't thrive at Petco Park. San Francisco has scored 23 runs in its 12 previous games at San Diego. The Giants did not score more than three runs in any of those contests.
Close games typically favor the Padres. They posted a 25-9 record in one-run games last year at Petco Park, helping them finish 48-33 at home overall.
Things to know about this game
• Giants first baseman Brandon Belt, who's trying to overcome a strained right groin and was available to pinch-hit Saturday, could start Sunday but more than likely won't return to the lineup until Monday at the earliest.
• Padres right-hander Tyson Ross, who makes his second start of 2015, was 2-0 with a 2.70 ERA in two starts against the Giants a year ago.
• Giants first baseman/left fielder Travis Ishikawa, recovering from a lower back strain, began his injury rehabilitation assignment with Triple-A Sacramento on Saturday.
• Padres left fielder Justin Upton has at least one hit in each of the team's first six games. He's tied with Nori Aoki of the Giants and Billy Butler of the A's for the longest hitting streak in the big leagues in 2015.
