SAN FRANCISCO -- Ryan Vogelsong will be ready to go when he takes the mound for the first time this season in Sunday's series finale against the Pittsburgh Pirates.

Just don't ask about it the day before.

"It's nothing personal, but I will not talk about a start the day before," Vogelsong said. "I don't like the stress, and I worry if I said something I shouldn't have."

Vogelsong did indicate everything was "good."

"I certainly have an appreciation for what he went through," catcher Buster Posey said. "I said last year that he's a guy you'd be hard pressed to find someone who works as hard as he does."

Posey relished catching Cain's one-hit gem

SAN FRANCISCO -- Buster Posey had a blast behind the plate as much as he did at the plate during the Giants' 5-0 victory over the Pittsburgh Pirates on Friday.

A day later and Posey, who was given the day off Saturday, was still smiling about Matt Cain's one-hit masterpiece. The catcher admitted contributing to a game like that was fun and memorable.

"He was really good," Posey said. "All four of his pitches were working and they were all sharp. Not one pitch was anything but crisp. If he missed, there was enough action to get away with it. It was a lot of fun."

Posey also contributed offensively, hitting an RBI double in his first regular-season appearance at AT&T Park since his unfortunate collision at home plate last year. He also scored when Aubrey Huff singled and said there was no hesitation regarding his restructured ankle.

"It felt good," said Posey. "For a while, I'm sure, there might be some thought when I hit the bag, but overall it was good."

Posey said since he began baseball-related activity during Spring Training, the ankle has been fine.

"There were a couple of times I could feel it before doing anything baseball related." he said. "I can walk around normally and I'm pleased with the way my ankle has felt the day after."

Worth noting

• Giants manager Bruce Bochy said Hector Sanchez will catch every time Barry Zito takes the mound, at least for the time being. "He did a great job with Zito last time out," Bochy said. "Why break it up?"

• Infielder Freeddy Sanchez has been playing in extended spring training games in Arizona without restrictions on his tender right shoulder. Bochy said, "He's close to going to Fresno to start rehabbing."

• Outfielder Melky Cabrera continues to impress the Giants' coaching staff. "He's been impressive from day one," said Bochy.
