SAN FRANCISCO -- Brandon Crawford was a scratch from Giants manager Bruce Bochy's lineup for the third consecutive day Friday with a sprained index and middle finger he injured Tuesday.
Crawford said he was available to pinch-hit, and Bochy added that he thinks the shortstop, who would only field in an emergency Friday, should be "playable" Saturday.
"It feels a little better, but not quite where I want it to be," Crawford said.
He played catch with head athletic trainer Dave Groeschner and threw as far as 120 feet, but "it still didn't feel good. I felt like there's not as much behind [the throws] as I'd like," Crawford said.
Crawford added that if he improves as much from Friday to Saturday as he did from Thursday to Friday, he should be able to start in Saturday's day game.
Torres bruises knee on slide vs. Marlins
SAN FRANCISCO -- Giants left fielder Andres Torres left Friday's game vs. the Marlins with a bruised right knee after trying to stretch a double into a triple in the sixth inning and is day to day.
Torres said he hit his right kneecap hard against the dirt when he dove into the base, but X-rays were negative. Head athletic trainer Dave Groeschner attended to Torres at third base before the outfielder left the game. Groeschner continued to examine the knee in the dugout.
"It was really sore," Torres said after the game. "I'm going to put some ice on it and see how it feels tomorrow."
Juan Perez replaced Torres, who went 2-for-2 with two doubles and a walk before the injury.
Torres said he feels added pressure to return to the lineup quickly considering San Francisco's current injury issues.
"I definitely [feel it]," he said. "I'm going to come in early tomorrow and see how I feel. I hope I'm good to go tomorrow."
Torres is hitting .270 with two home runs and 15 RBIs in 60 games this season.
Pagan could need surgery for ailing hamstring
SAN FRANCISCO -- Surgery again looms as a possibility for Angel Pagan, the Giants center fielder and leadoff hitter who aggravated his strained left hamstring in a Minor League injury rehabilitation appearance Thursday night.
Giants manager Bruce Bochy said after Friday's 6-3 loss to Miami that the organization's braintrust will thoroughly examine every option regarding Pagan, who signed a four-year, $40 million contract in the offseason.
"Sure, we'll get it checked out again, but in the next day or two, we're going to have to decide which way we're going to go with him as far as treatment," Bochy said.
Asked if surgery was being considered, Bochy responded without hesitation.
"Sure," he said. "No question it's an option. That's what we'll talk about the next day or so and figure out what is the best option."
Pagan, who has been sidelined since May 25, said last week in Atlanta that surgery had been discussed for his injury, which he said hurt most where the hamstring meets the bone at the side of the knee. But he and the club opted for intensive treatment and rehab.
Bochy thus refused to second-guess sending Pagan, who was appearing in his first rehab game, on his assignment with Class A San Jose. Bochy pointed out that Pagan, who turns 32 on July 2, passed all the preliminary physical tests that are required before a player can begin a rehab stint.
"He said he felt great," Bochy said.
Before Friday's game, Bochy spoke briefly to Pagan, who was carted off the field after pulling up when he tried to sprint to first base in San Jose's game at Stockton.
"He seemed all right. A little down," Bochy related. "I think he's hoping, like the rest of us are, for good news."
Gaudin sore but optimistic about next start
SAN FRANCISCO -- Chad Gaudin woke up with a lot of soreness Friday, but it wasn't just the bruised right upper forearm that forced him to leave Thursday's start that ailed the right-hander.
In addition to the forearm, for which Gaudin sported a lymphatic sleeve to help with the swelling and bruising, his lower back ached from taking a different line drive there in the first inning Thursday. While the back is not jeopardizing Gaudin's next start, the forearm is another matter.
"I'll be honest. It's probably a little too soon to say he's a definite [to make his next scheduled start Tuesday]," manager Bruce Bochy said.
Gaudin did not throw at all Friday and let the arm rest, but expects to throw Saturday and complete his bullpen session Sunday.
"I'm pretty optimistic about it," said Gaudin, who added that he's fortunate he did not break any bones.
Casilla progressing well, could return soon
SAN FRANCISCO -- Reliever Santiago Casilla, who has missed a month after a cyst was removed from his right knee, is progressing quicker than the Giants had expected and could be available by the end of the team's next road trip.
The setup man, who recorded a 1.89 ERA in 21 games prior to the surgery, will throw a bullpen session Saturday and could throw to hitters Monday in Los Angeles.
If all goes well, Casilla could begin a rehab assignment next week and rejoin the team after two or three appearances, manager Bruce Bochy said.
Bochy said Casilla's return could be "pretty close" to the end of the next road trip, which concludes in Cincinnati on July 4, 10 days before the All-Star break.
Surkamp doing well in rehab from Tommy John surgery
SAN FRANCISCO -- Giants left-hander Eric Surkamp estimated Friday that he'll need five more outings before he can throw 100 pitches, an average starter's workload.
Surkamp continued to demonstrate his steadily increasing arm strength Thursday night in Class A San Jose's game at Stockton, allowing two hits in four innings while walking none and striking out three.
Surkamp, who underwent Tommy John elbow surgery last July, said that he has regained the fastball velocity -- 87 to 89 miles per hour -- which he possessed before his operation.
"I still feel like my mechanics are a little bit out of whack," Surkamp said in a visit to the Giants clubhouse. Noting that he's still trying to sharpen his curveball, he said, "I'm spinning it good, but location-wise, I'm not there yet."
Surkamp's statistics indicate that he's not struggling at all. In four appearances with San Jose, he has recorded a 3.18 ERA while walking two and striking out 11 in 11 1/3 innings. His WHIP (walks and hits per inning pitched) is an impressive 0.79.
Surkamp is a key figure in the Giants' plans, given the state of their starting rotation. Three of its members aren't guaranteed to return in 2014: Tim Lincecum, who'll be eligible for free agency at the end of the season, and Barry Zito and Ryan Vogelsong, whose contract options are controlled by the club. Surkamp, 25, showed flashes of potential at the end of the 2011 season, when he went 2-2 with a 5.74 ERA in six starts for San Francisco. Should he avoid physical setbacks, he could emerge as a contender for a spot in the rotation next spring.
