SAN FRANCISCO -- The Giants announced their 234th consecutive sellout Thursday night at AT&T Park, but it was clear throughout a 4-2 loss to the Arizona Diamondbacks that several thousand buyers opted to stay home. Those who show up over the next few days won't be watching the team's biggest attraction.

X-rays on catcher Buster Posey's swollen right ring finger revealed a small fracture at the tip, one that will keep the reigning MVP out of the lineup for several days. Posey said he can continue playing as long as the discomfort is manageable.

"From what I'm hearing from the trainers and doctor, it's something that hopefully in a couple of days, once it calms down, I'll be able to play through it," Posey said. "I'm hopeful that it's manageable. I think it'll be all right."

Posey was hurt Tuesday night in San Diego when a Madison Bumgarner pitch deflected off the plate and hit his bare hand, ripping his fingernail. Posey was replaced during that game as his finger swelled up and hasn't swung a bat since.

He said he thought he would be able to throw without any problems and anticipated being fine at the plate once he returned to the field. The Giants dropped to 62-78 with the loss, and there's little reason for Posey to push himself, but he said doctors have told him that there's no risk in playing through the injury.

"It's not displaced or anything, so it'll just correct itself," he said.

Manager Bruce Bochy likely wishes he could say the same for the rest of a team that continues to play sloppy baseball. Ryan Vogelsong didn't make it out of the fifth inning Thursday night, and the Giants ran into several outs on the bases while dropping the opener of a seven-game homestand.

Vogelsong cruised into the fifth but gave up four runs on a string of five two-out hits and a walk.

"I made some bad decisions on pitches and on selection and on top of that I didn't execute the ones I picked," he said. "(Catcher Hector Sanchez) made some right calls, and I shook him off. I didn't execute very well, and those two are really not a good combination. It's disappointing.

"The wheels fell off, and I couldn't get it back together. That's all on me. This loss is all on me."

Well, not quite. Diamondbacks right fielder Gerardo Parra played a starring role, too.

Parra cut down Brandon Crawford at the plate in the third inning and appeared to throw out Pablo Sandoval at the plate in the fourth. Sandoval was incorrectly ruled safe, giving the Giants a 2-0 lead. As the Giants tried to rally later in the game, Brandon Belt was thrown out at second after Parra quickly scooped up a shot off the right field wall.

"There's not a better arm in baseball," Bochy said. "He's as accurate as any I've seen throw the ball. He's electric, and he showed it tonight."

  • Left-handed reliever Jeremy Affeldt went through fielding drills Thursday afternoon to test his strained groin and is scheduled to throw 40 pitches to hitters before Friday's game. Bochy said Affeldt is close to being brought off the disabled list.

    Soon after Affeldt worked out, right-hander Chad Gaudin (carpal tunnel) threw a bullpen session. Bochy was confident that Gaudin would return later this month but was unsure if it would be in the rotation or out of the bullpen.

    "If he's healthy, we'd love to put him out there," Bochy said. "I know he would like to get out there and finish the season strong."

  • Earlier this week, Bochy removed veteran Barry Zito from the rotation for the second time. He said Zito came into his office Wednesday to express his appreciation to the coaching staff for giving him the three extra starts when Gaudin was put on the disabled list Aug. 20.

    "Barry has been so good and such a standup guy," Bochy said. "Here's a guy who had three rough starts, but he thanked me for putting him out there again. That's the type of person he is."

    Zito's seven-year contract with the Giants expires at the end of the season, and there had been some thought that he would get one final home start down the stretch, but Bochy said that has not been discussed by the coaching staff.

  • Sandoval pulled off a rare feat Wednesday when he hit three home runs in a win over the San Diego Padres. According to the Giants, Sandoval is just the sixth player in MLB history to have three-homer games in the regular season and postseason. The others: Babe Ruth, George Brett, Reggie Jackson, Albert Pujols and Adrian Beltre.
