Infielder Abreu begins rehab stint at Triple-A

SAN FRANCISCO -- Infielder Tony Abreu, originally in the mix to make the Giants as an extra infielder during Spring Training, finally gets a chance to show off his skills.

Abreu, on the disabled list since March 22 with a left knee sprain, began a rehab assignment with Triple-A Fresno on Friday night.

"It's good to get him going on his rehab," Giants manager Bruce Bochy said. "It took longer than anybody thought. For him, he's in Spring Training."

The 28-year-old has spent parts of four years in the Major Leagues, most recently with the Kansas City Royals last year.

"There is no target date for him," Bochy said. "We want him to continue to get better, with no more setbacks."

Abreu is a career .252 hitter with four home runs and 46 RBIs in 168 games. He's also played for the Los Angeles Dodgers and the Arizona Diamondbacks.

World Series, Scutaro gave Peguero a boost

SAN FRANCISCO -- Giants outfielder Francisco Peguero said being able to sit in the dugout during last year's run to the World Series title, along with advice from Marco Scutaro, made him a better player.

Peguero, who spent Spring Training with the Giants, was recalled from Triple-A Fresno before Friday night's game with the Los Angeles Dodgers.

"I had a great Spring Training and started well," said Peguero, who batted .415 with two homers and 14 RBIs in 16 games with Fresno. "The experience of last year helped me a lot. It helped me control my nerves and emotions. That whole experience helped me."

Perhaps the best advice came from Scutaro, the Giants' postseason hero.

"He helped me to make better contact and be more consistent," Peguero said.

Scutaro said it was easy to help Peguero.

"The guy has a world of talent," Scutaro said. "He just needs to be more consistent."

Peguero, who turns 25 on June 1, made his Major League debut last Aug. 25, appearing in 17 games. He hit .188 and stolen three bases.

"He's been playing well," Giants manager Bruce Bochy said. "He gives us some flexibility in the outfield and with his speed."

The Giants also reinstated left-hander Jeremy Affeldt (strained right oblique) from the 15-day disabled list. Catcher Hector Sanchez was optioned to Fresno, while right-hander Sandy Rosario was optioned following Wednesday's game.

Sanchez sent down to get more playing time

SAN FRANCISCO -- Giants manager Bruce Bochy wants catcher Hector Sanchez to play, and play a lot.

"Pinch-hitting and playing here and there is just not going to do it," Bochy said Friday after Sanchez was optioned to Triple-A Fresno. "Sanchez needs some playing time."

Sanchez missed a significant portion of Spring Training with a right shoulder problem and just never got going.

He appeared in 11 games with the Giants this year and batted .150. Sanchez, 23, made his Major League debut in 2011.
