SAN FRANCISCO -- Angel Pagan was taken out of the Giants' game vs. the Dodgers before the sixth inning Friday because of a right hamstring strain. It wasn't clear when he suffered the injury.
Andres Torres, who entered the game in left field as part of a double-switch in the fifth, replaced Pagan in center field, while Francisco Peguero took over in left and in Pagan's leadoff spot.
"He's got a mild strain on his upper hamstring," manager Bruce Bochy said after the game. "He's questionable for tomorrow. That's how mild it is. We'll wait until he gets in here tomorrow and see where he's at."
Giants may keep 13 pitchers when Mijares returns
SAN FRANCISCO -- Manager Bruce Bochy believes the Giants' bullpen is doing so well that it is presenting a problem, albeit a good one.
When reliever Jose Mijares returns from the bereavement list, Bochy will have a tough decision in picking the player who no longer fits on the active roster. As a result, Bochy is considering going with 13 pitchers. The Giants currently have 12.
The decision will come down to how the starting pitchers are faring and how deep they're pitching into games, Bochy said.
"What's more important for us right now?" Bochy said, sharing the question he'll soon face. "Having an extra pinch-hitter, or have an extra pitcher?"
In its last 14 games, San Francisco's bullpen has notched a 1.44 ERA. This season, it owns the second-best ERA (2.44) in the National League behind Atlanta.
Kentucky Derby captivates Giants players
SAN FRANCISCO -- Walking into the Giants clubhouse Saturday afternoon, there was more chatter about the Kentucky Derby than anything else.
Angel Pagan and Tim Lincecum were pouring over a newspaper showing odds. Pablo Sandoval's eyes were fixed on one of the TVs showing prerace coverage.
"That's my horse right there!" was one of the many shouts heard in the clubhouse and during pregame stretching with the race shown on AT&T Park's scoreboard.
For Pagan, this is no fling. He's been a fan for a while.
"I liked racing since I was like 8," he said. "My dad used to take me. It's just a fun thing to do. It's relaxing."
Pagan said he would root for Verrazano, whose jockey, John Velazquez, is from his native Puerto Rico. Verrazano finished 14th out of the 20 horses.
Posey shrugs off eventful night at home plate
SAN FRANCISCO -- A day after being involved in two important plays at the plate during the Giants' series-opening 2-1 win against the Dodgers on Friday, catcher Buster Posey offered insight into both.
The play that made the AT&T Park crowd hold their breath for a second came in the second inning, when Posey received a throw from first baseman Brandon Belt and tagged out A.J. Ellis, avoiding a big collision. It was a home-plate collision with Scott Cousins that broke a bone and tore three ligaments in his left leg on May 25, 2011.
On the play in which he tagged out Ellis: "You're kind of blind to the runner," Posey said. "The ball's coming from the right side of the infield and you're just trying to be like a middle infielder and make the tag."
Posey was tagged out at home trying to score on a Hunter Pence hit, ending the inning. Posey slid with his left leg tucked, which, he said, is how he would typically slide. He was asked if he would change anything about that play.
"I wish I was faster, so I would change that," Posey said.
Posey is one of the faces of the franchise, and because of that 2011 injury, fans are still crossing fingers during such plays at the plate. But, Posey said, he is only concerned executing his job.
"I don't sense that," Posey said of others' worry. "When you're in the moment, you're just trying to make a play."
• Giants starting pitchers have not earned a victory in 10 games, since Barry Zito's win April 21 against San Diego. Bochy said it's not too important to him whether his starters get the statistic, as long as they put the team in position to win.
"When you look at a game like last night, Zito doesn't get the win, but we don't get the win without him."
• Ryan Vogelsong, previously 0-for-10, notched his first hit of the season Saturday with a single up the middle in the third inning.
