Live BP session goes well for Vogelsong

SAN FRANCISCO -- Ryan Vogelsong's next checkpoint on his road to physical recovery could be appearing in an Arizona League game Tuesday, which might put the right-hander on course to resume pitching for the Giants on Aug. 9 or 10, manager Bruce Bochy said.

Bochy spoke Saturday after watching Vogelsong throw 35 pitches of batting practice to outfielder Gregor Blanco and coaches Roberto Kelly and Shawon Dunston. Vogelsong warmed up for that session by tossing 40 pitches in the bullpen, hiking his total to 75. Bochy said that the Giants want Vogelsong to build enough stamina to throw 80 to 85 pitches before they'll consider activating him from the disabled list.

Bochy said that Vogelsong might follow the Arizona League stint by pitching an injury rehabilitation game for Class A San Jose. Bochy reiterated that Vogelsong likely will travel with the Giants to Washington, D.C., on July 28 for their White House visit the next day, then would pitch a game or two for Double-A Richmond.

After that, barring setbacks, Vogelsong might be ready to be reinstated from the DL, where he was assigned after fracturing the pinkie on his throwing hand May 20.

Vogelsong compared his throwing session to an early Spring Training bullpen stint in which regaining sharpness and building arm strength would be primary goals.

"I took out of it what I wanted to," said Vogelsong, San Francisco's No. 5 starter before being injured. "I came out of it healthy and I was able to work on my pitches."

Disabled list possible after Affeldt strains groin

SAN FRANCISCO -- Giants left-hander Jeremy Affeldt strained his left groin during the sixth inning of Saturday night's game against the Arizona Diamondbacks and could be headed for the disabled list.

Giants manager Bruce Bochy said after San Francisco's 4-3 victory over Arizona that Affeldt underwent a postgame MRI exam. Results wouldn't be known until Sunday morning, Bochy said. But, referring to the nature of Affeldt's injury, Bochy added, "That's never a good area. It's a possible DL."

Affeldt replaced reliever George Kontos with one out, runners on first and second base and the Giants clinging to a 4-2 lead. Affeldt coaxed a fly to right field from the first hitter he faced, Cliff Pennington, but grabbed himself in pain while throwing a 3-1 fastball to the next batter, pinch-hitter A.J. Pollock, who fouled off the pitch.

Bochy and assistant athletic trainer Mark Gruesbeck examined Affeldt briefly before the reliever left the field.

Affeldt, 1-4 with a 3.51 ERA in 38 appearances, endured a stint on the 15-day disabled list from April 15-May 3 with a strained right side.

Crawford plays despite bruised left foot

SAN FRANCISCO -- Brandon Crawford's playing status was rated as day to day Saturday by Giants manager Bruce Bochy, one day after the shortstop sustained a bruise on his left foot during an eighth-inning collision with Arizona right-hander Heath Bell.

Yet Crawford felt well enough to pinch-hit in Saturday's sixth inning and remain in the game at short as San Francisco confronted the Arizona Diamondbacks.

The afflicted area is on the outer left edge of Crawford's foot, which he reported as feeling sore. Bochy said that Crawford's foot also was somewhat swollen.

Bochy affirmed that Crawford was out of Saturday's lineup due primarily to his injury and not because of the lefty-vs.-lefty matchup he would have faced against D-backs starter Wade Miley.

Crawford, who has appeared in 91 of San Francisco's 96 games, was hurt after he hit a two-out comebacker to Bell. Hustling up the first-base line, Crawford ran toward the bag and slid into it feet-first as Bell, who's listed at 250 pounds compared to Crawford's 215, tumbled over him. Technically, Crawford was mildly spiked, since a hole remained in his left shoe where one of Bell's cleats penetrated it.

Worth noting

• Infielder Joaquin Arias (appendicitis) resumed performing baseball-related activities Saturday. Bochy said Arias, who underwent an appendectomy July 7 and is on the disabled list, hit off a tee and took some grounders during batting practice.

• Until Friday, when the Giants outlasted Arizona, 2-0, they hadn't won a game in which they didn't score after the first inning for the first time since June 19, 2006. That afternoon, Matt Cain no-hit the Angels for 7 2/3 innings until Chone Figgins singled. San Francisco prevailed, 2-1, as Cain left the game after finishing the eighth, backed by first-inning RBIs from Barry Bonds and Steve Finley.

• Newcomer Jeff Francoeur was asked if he'd buy pizza for fans sitting nearby at AT&T Park when he's stationed in left field. While playing for Kansas City in April 2012, Francoeur purchased 20 personal pizzas and had them delivered to fans in the bleachers at Oakland's O.co Coliseum. "I have to see," Francoeur said cheerfully. "There are a lot more people here than in Oakland."
