Bochy to keep sitting Posey to help him stay healthy

SAN FRANCISCO -- With the season-ending stretch approaching and the future of his All-Star catcher on his mind, manager Bruce Bochy said he will continue to sit Buster Posey on occasion despite his second-half production at the plate.

"You have to do what's right, so it's not a tough call," Bochy said. "He's going to get another day off, and even a couple more. I know it's not easy. We all want Buster out there, believe me. I want to see him out there, too."

Posey responded in a big way after taking a day off on Friday, going 2-for-4 with a two-run home run during Saturday's 9-3 win against the Rockies. His .443 average and 32 RBIs since the All-Star break are tops in the Majors.

"It benefits the player," Bochy said. "You wear him down to the point where now it takes a week to get them back and get their legs back. It's worked out very well. He got a day off and then had a big day yesterday. There's no way he could have caught a day game in St. Louis and then caught a night game and a day game. It's just not going to work."

With Sandoval returning, infield may be shuffled

SAN FRANCISCO -- Giants manager Bruce Bochy said before Sunday's game that Pablo Sandoval "feels great" after two rehab appearances for Class A San Jose, and that the All-Star third baseman is on track to rejoin the Giants on Monday.

Sandoval played seven innings at third base on Saturday, but for the second game in a row did not get any ground balls.

"That's two games in a row," Bochy said. "It's hard to believe that in two games he didn't get any ground balls."

Bochy said he anticipates the makeup of the infield changing by a game-to-game basis, with Sandoval getting playing time at both third base and first, and Marco Scutaro playing at different infield spots.

"It's nice to have the versatility where you can move guys around," Bochy said. "I think that'll play a major role down the stretch here. If somebody gets a little nicked up or is not seeing the ball well, it's nice to have this depth."

While Scutaro has played shortstop in the past, Bochy said that Brandon Crawford's hold on the position is still safe and that the second-year shortstop will continue to get "the lion's share" of the playing time at the position.

"You have to like the way he's playing defensively and swinging the bat," Bochy said.

Giants look to improve hitting in day games

SAN FRANCISCO -- Saturday's 9-3 offensive onslaught against the Rockies was noteworthy for more than the Giants' rare outburst at the plate at home. The 13 hits came in a day game, during which San Francisco has struggled for the most part this season.

The Giants hold a collective .241 average during day games, which ranks 12th in the National League, compared to their NL-leading .277 average during night games.

"I think if you ask most of them, they'd say they prefer night games," manager Bruce Bochy said before Sunday's game. "They get to sleep in and go through their routines a little bit easier compared to coming in early and trying to get ready. But some guys prefer day games. I know I do."

The disparity between day and night games is even more confounding considering how the air is considered to be thinner during the day at AT&T Park, with the heavier moist air at night considered to be detrimental to hitters.
