ANAHEIM -- Giants manager Bruce Bochy had to knock on wood as he said it, but he has been pleasantly surprised with the season his closer, Santiago Casilla, is having so far.
In place of the injured Brian Wilson, who has been on the disabled list since April 16 after undergoing his second Tommy John surgery, Casilla has been one of the league's best closers. His 19 saves are one behind the Braves' Craig Kimbrel for tops in the National League, and his 1.32 ERA (four runs in 27 1/3 innings) is the fourth-lowest among NL relievers.
"I'll be honest, I was comfortable with him there having some knowledge from the previous year," Bochy said. "But I'll say this, it's been a little smoother of a ride than I thought it may be with him."
Casilla (1-2) has converted 14 straight save opportunities for the Giants, and though it might be a surprise to Bochy that the righty has been as great as he has been, the manager said he feels the transition from a quality setup man to a quality closer is often a smooth one.
Just as long as he has the stuff to do it.
Huff progressing well from sprained knee
ANAHEIM -- Giants outfielder Aubrey Huff, who has been on the disabled list since June 15 with a right knee sprain, is up and walking around well, manager Bruce Bochy said.
"He's doing better. We'll see him Friday, but he's walking around well," Bochy said. "I can't say when we're going to activate him, but he's making the type of progress we thought."
Huff incurred his injury after jumping over the dugout railing while celebrating Matt Cain's perfect game. It's his second stint on the DL this season, as he missed 13 games in April and May with an anxiety disorder.
In 58 at-bats this season, the 35-year-old has a .155 average with one home run and five RBIs. He has started just 14 games in 2012.
Runzler begins rehab at Triple-A
ANAHEIM -- Left-handed reliever Dan Runzler, who has been on the disabled list all season with a strained left latissimus dorsi muscle, made his first rehab appearance with Triple-A Fresno on Tuesday night.
In his one inning of relief, Runzler allowed two runs on three hits, including a home run.
"He was a little rusty, gave up some runs," manager Bruce Bochy said. "But the velocity was good, 92-94."
In 27 1/3 innings with the Giants last season, Runzler had a 6.26 ERA with 16 walks and 25 strikeouts. In 2010, he posted a 3.03 ERA with 37 strikeouts in 32 2/3 innings.
The Giants don't plan on just bringing up the lefty when he's ready this season, however.
"It's a baseball decision, as we need him," Bochy said. "This officially starts his rehab. So we have to make that decision once his rehab is over."
With a single and a double in his first two at-bats Tuesday night, left fielder Melky Cabrera became the fastest San Francisco Giants player to 100 hits, completing the feat in just 291 at-bats. He broke the previous record of 295 at-bats set by Willie Mays in 1958.
During his five-game hitting streak, Cabrera is batting .435 (10-for-23) with one home run and four RBIs. His .369 season average is tied for first in the Majors, and his three hits also gave him his NL-leading 33rd multihit game of the season.
Reliever George Kontos, who is currently away from the team attending his grandfather's funeral in the Chicago area, will be back with the team Friday, Bochy said.
The team decided not to place Kontos on the bereavement list, which would force the righty to miss at least three days. Instead, they were one pitcher short in the series finale with the Angels on Wednesday.
