After clinching the National League West on Saturday, manager Bruce Bochy saw Sunday afternoon as the perfect day to give his players a breather with a day off Monday.
"It's important to keep the same focus ... of wanting to play the game hard," said catcher Buster Posey, who had played 27 consecutive games before driving in a run with a pinch-hit forceout in the ninth inning Sunday.
Tim Lincecum gets the start after being scratched from his originally scheduled start Sunday afternoon.
Lincecum has turned things around lately and has compiled a 3.01 ERA with 54 strikeouts and 28 walks in 59 2/3 innings since July 31.
Taking the mound against Lincecum and the Giants will be Josh Collmenter. He gets the start in place of rookie left-hander Tyler Skaggs, who was scratched after Monday night's game.
Pitching out of the bullpen for the last two months, Collmenter last started July 27 against the Mets. In 26 appearances this season, nine of which have been starts, the right-hander is 4-3 with a 3.92 ERA.
After taking a 4-2 loss to the Rockies on Monday, the D-backs currently sit 5 1/2 games back of the Cardinals for the second National League Wild Card spot.
D-backs: Young hopeful to return from quad strain
Outfielder Chris Young ran some sprints prior to batting practice on Monday and is hopeful that he can be back from a right quadriceps injury before the end of the season.
Young hurried back from the strain, which lasted just one play as he aggravated it running down a fly ball on the first play of the game.
"It kind of gives you a sign that you don't want to rush it so you try to be smart, but at the same time you want to get back on the field," Young said. "I'm just trying to be a little smarter about things than I have been in the past. It's actually weird for me because I'm used to coming back and pushing through some pain and playing through some things and this is the first time that I haven't been able to run through it or just tough it out per se, because it just didn't allow me to do it. It's a different experience for me."
Second baseman Aaron Hill was out of the lineup on Monday with an upper respiratory flu that has been going around the clubhouse.
Giants: Entire rotation will be on playoff roster
All five San Francisco starting pitchers will be on the postseason roster, manager Bruce Bochy said Sunday.
One of those five will be moved into the bullpen with Matt Cain and Madison Bumgarner locks to stay in the rotation.
As for the odd man out, that leaves Tim Lincecum, Ryan Vogelsong and Barry Zito, who was omitted from the roster for the entire 2010 postseason.
Pitching coach Dave Righetti and Bochy are discussing how to set up the playoff rotation and whether or not the rest of the regular season will dictate the order.
Lincecum missed Saturday's postgame division-clinching celebration because he was originally scheduled to pitch the following afternoon and was urged to go home to rest.
D-backs third baseman Chris Johnson was out of the lineup Monday after being hit in the left hand by a pitch in Sunday's game. X-rays of the hand were negative and Johnson had a heavy wrap on the hand.
