Sandoval out of lineup for Toronto finale

TORONTO -- With an upcoming off-day Monday, Giants manager Bruce Bochy decided to leave third baseman Pablo Sandoval out of the lineup Sunday vs. the Blue Jays to give his slugger a two-day rest.

"Pablo is fine, giving him a day off," Bochy said. "He hasn't had a day off in a while, [and] this will give him two days to hopefully freshen him up."

Sandoval, who hit .330 with 90 RBIs last season, is currently hitting a respectable .280, though with only 29 RBIs. The decline in production prompted Bochy to move Sandoval into the fifth spot in the lineup just over a month ago -- a place where he will remain in the foreseeable future.

"Right now I'm probably going to leave him where he is down there," Bochy said. "I think he's getting more and more comfortable. Sometimes he gets a little fast with his stride and gets himself in trouble, but he's getting close."

Bochy also cited Blue Jays starting pitcher Shaun Marcum as another reason for leaving Sandoval out of Sunday's contest.

"[Marcum's] numbers are [significantly better] between righties and lefties," Bochy said. "If you're going to give him a day, it would be today -- get another right-handed batter in there."

While Sandoval is a switch-hitter, he is hitting only .229 with no home runs from the right side.

"I think it kind of goes year-to-year with switch-hitters," Bochy said. "You go back to Randy Winn -- two years ago he did such a great job right-handed and last year it was such a struggle for him. Sometimes you just get out of sync."

Posey confident despite hitting slump

TORONTO -- Since being called up May 29, highly touted Giants rookie Buster Posey has done everything right. The 23-year-old has hit the ball with conviction, hitting .310 over 75 at-bats, while playing great defense at both first base and catcher. However, like many other rising stars before him, Posey is beginning to experience the growing pains that tend to parallel a transition to the big leagues.

After hitting .429 through his first 13 games, Posey has since slowed down considerably, going 1-for-21 with a walk over six games entering Sunday's contest against the Blue Jays.

Despite his recent hiccup in production, Posey believes he is still making good swings.

"The thing that is frustrating is I feel like we've been in some ballgames we should have won," Posey said. "I mean, I get in my head here and there to bring in some runs -- that's been frustrating -- [but] I've felt pretty good at the plate. I've hit some balls hard, just right at guys.

"It's one of those things -- try to control what you can and not worry about what you can't control."

In Friday's contest against the Blue Jays, Posey was robbed by third baseman Edwin Encarnacion on a ball hit sharply down the line. On Saturday, Posey was once again the victim of outstanding defense, as shortstop Alex Gonzalez made a sliding grab on a ground ball hit up the middle.

Giants manager Bruce Bochy remains confident that it's only a matter of time before the youngster starts finding some gaps. He also commended Posey for the consistent approach and attitude he brought to the plate in both games as well as batting practice.

"That's a great compliment," Posey said. "That's something that I try to do and it's something that's not easy to do, because when you do have a little hiccup, it's easy to start wanting to change stuff and try to mix stuff up. That's the goal though -- try to stay consistent."

First base fine, but Posey wants to catch

TORONTO -- When the Giants re-signed catcher Bengie Molina in the offseason, it raised questions as to where top catching prospect Buster Posey would fit into the mix.

Posey, who was called up May 29 from Triple-A Fresno, has temporarily found a new home at first base -- a role he is learning to embrace.

"I'd say I prefer catching, but I don't mind first," said Posey, who has started 18 of his 19 games at first base this season.

While the transition has been nearly seamless for Posey, he said he still remains a catcher at heart.

"I enjoy catching just from the mental aspect of it, from working with the pitchers and trying to get on the same page with them," Posey said. "You're more involved on the defensive side of the ball."

Posey also added that it has been difficult to stay sharp at the catching position, with most of his time being occupied at first base.

"There is really no way you can," Posey said about remaining prepared. "You can try to follow along out there on defense, but at the same time you're out there thinking about other stuff."
