Bochy, Flannery remember good friend Gwynn

CHICAGO -- Giants manager Bruce Bochy and third-base coach Tim Flannery witnessed Tony Gwynn's excellence and effervescence firsthand.

More than almost anybody else, they understood what distinguished Gwynn, whose death from cancer was announced Monday. They were struck not just by the grace of the man's swing, which earned him eight National League batting titles, but also by the grace of his personality.

Bochy, who managed Gwynn in San Diego from 1995-2001, praised the Hall of Famer's accessibility to the fans.

"He's getting recognized as one of the great guys ever in the game," Bochy said Tuesday. "Ultimately that's what you want to be known for."

Bochy lives approximately a half-mile from Gwynn and his family in suburban San Diego.

"I regret now not having spent more time with him," Bochy said. "It's a great loss for baseball and San Diego."

Flannery, a teammate of Gwynn's from 1982-89, cherished his "childlike" enthusiasm and perspective. Flannery also illustrated Gwynn's renowned work ethic by pointing out that the .338 lifetime hitter was not only the first player to use video equipment for analyzing opponents, but also stood alone in knowing what to seek.

"A lot of guys now will stare at that thing and have no idea what they're looking at," Flannery said.

Stiff back keeps Pagan out vs. White Sox

CHICAGO -- Back stiffness forced Giants center fielder Angel Pagan from the lineup for the second straight game Tuesday as San Francisco opened its two-game Interleague series against the Chicago White Sox.

"He's making a little progress, but not as much as we hoped," said Giants manager Bruce Bochy, who rated Pagan's playing status as day to day.

Bochy said Pagan underwent an MRI that revealed inflammation, adding that he wanted to see the leadoff hitter's ailment "calm down" before he would rejoin the lineup.

Pagan also missed starts June 8-9 with a leg ailment. He entered Tuesday batting a team-best .307 with 11 stolen bases in 14 attempts.

Cautious Giants have Posey serve as DH

CHICAGO -- Buster Posey felt well enough to catch Tuesday's series opener for the Giants, but was limited to designated-hitter duties as a precaution.

"I'm all good," Posey said, using both hands to flash the universal thumbs-up gesture for optimism.

Giants manager Bruce Bochy agreed that Posey, who left Sunday's game against Colorado early after being rocked by a foul tip off his facemask, could have caught against the White Sox. But Bochy said that using Posey strictly as a DH "was my call. I wanted him to get an extra day [off] in case he takes a shot off the mask."

Bochy said Michael Morse will replace Posey as the Giants' DH for Wednesday's series finale. That would give Morse essentially two days of rest, since Thursday is a scheduled off-day.
