Getting his team set for playoffs, manager Bruce Bochy is making sure the Giants stay focused and continue to play winning baseball.
"That's how you should play," Bochy said. "You can't drop your guard. It's like a pitcher with a big lead. You can't just throw fastballs and give in. As a club, you have to do the same. Every game is important until you get it done. It's the only approach you can have."
While Tim Lincecum was scheduled to start Sunday's contest, the Giants will instead turn to Yusmeiro Petit and give Lincecum extra rest, now that they have clinched the NL West.
Sunday's outing will be Petit's first appearance with the Giants this season. He last pitched in the Majors with the D-backs in 2009. In 36 career starts, the right-hander is 10-20 with a 5.57 ERA.
Eric Stults gets the start in the series finale for the Padres, taking Andrew Cashner's place in the rotation after Cashner was shut down for the rest of the season.
Stults was initially scheduled to pitch Tuesday, but will jump a spot in the rotation, which had consisted of six pitchers before Cashner's season was cut short because of a strained right lat muscle.
In a loss on Tuesday against the D-backs, the left-hander allowed three runs on five hits in six innings of work. While he surrendered just three walks, two of those free passes came around to score and proved to be the difference in a 3-2 loss.
"The thing tonight was a couple of walks and two-out hits," Stults said after the outing. "The biggest disappointment for me was just the walks."
Padres: Grandal scratched
Catcher Yasmani Grandal was scratched from the Padres' lineup on Saturday following the team's batting-practice session, after he took a foul ball off his jaw while catching in the seventh inning of Friday's game.
Manager Bud Black said before Saturday's game that he wouldn't make a final decision on Grandal's status until after batting practice.
"He's feeling better, but we'll see," Black said. "I'm going to let him go through [warmups] and see how he feels. We could change it; I want to make sure that he feels good."
Grandal was replaced by John Baker, which marked Baker's 50th start behind the plate for the Padres this season. Grandal did pinch-hit in the ninth inning, grounding into a fielder's choice.
Giants: Crawford finding success against left-handers
Brandon Crawford was in the Giants lineup for Saturday's game against left-hander Andrew Werner after finding recent success against lefties.
While Joaquin Arias started at shortstop in 17 of the Giants' previous 20 games against left-handers, Crawford has quietly collected 10 hits in his last 25 at-bats against lefties. He went 1-for-3 in Saturday's game.
"He's done a great job," Bochy said on Saturday. "That's why he's in there tonight. It's a compliment to Craw, how he's adjusted off left-handers. He's really made some adjustments, starting in Spring Training. He's worked hard. Now he's swinging the bat really well. He's made himself into a sold player from both sides."
The Padres are now 9-16 (.360) in Saturday games this season, their worst winning percentage on any day.
The Giants have posted a 36-16 (.692) record this season when facing left-handed starting pitchers, the highest winning percentage in the Majors.
