SAN FRANCISCO -- The Giants started Marco Scutaro at the leadoff spot against the Mets on Monday as the club continued its search for consistent offense while trying to break out of its 20-inning scoreless streak.

Scutaro had started 36 games at the leadoff spot for the Rockies this season, batting .235 with a .295 on-base percentage. In 350 career starts at the top of the order, Scutaro has a .273 average and a .349 on-base percentage.

"He's done so much leading off and he's had success," manager Bruce Bochy said. "I think it's fair to say we've been struggling. We need to get things clicking. Fortunately we have a couple guys who can lead off."

In his third game with the Giants, Scutaro was the fifth leadoff hitter the Giants have had this season, along with Gregor Blanco (65 games), Angel Pagan (25), Nate Schierholtz (7) and Justin Christian (4).

The switch in the lineup came after the Giants were shut out in the last two games of the three-game sweep at the hands of the Dodgers with Pablo Sandoval being sidelined since straining his left hamstring against the Padres on Tuesday.

"We were swinging the bats OK until that [Dodgers] series," Bochy said. "One guy goes down, that affects the club a little bit, but you need to be able to bounce back."

The Giants' four-game losing streak entering Monday matched a season high, and they batted a collective .201 (27-for-134) in that stretch.

"Offensively, we're out of sync right now," Bochy said. "Right now what I want to see is these guys swinging the bats with confidence."

Torres 'excited and happy' for San Francisco visit

SAN FRANCISCO -- Nearly four hours before the first pitch of Monday night's Giants-Mets game, Andres Torres already was busy. After all, he had many friendships to celebrate and acquaintances to renew.

Torres not only shook hands and exchanged hugs with numerous Giants players, but also greeted a security guard and members of the grounds crew.

"I'm really excited and happy to be back here," said Torres, the outfielder who was traded with right-hander Ramon Ramirez to the Mets for outfielder Angel Pagan last Dec. 5.

Because Torres was recovering from a hamstring injury at the Mets' training base in Florida when San Francisco visited New York in April, this was his first opportunity to exchange pleasantries with Giants personnel since the trade. One of the more popular Giants among teammates and fans during his 2009-11 stint with San Francisco, Torres expressed gratitude for the support he received.

"I always wish them the best. Everyone," he said. "I'm always thankful for everything they did for me and I really appreciate that."

Torres, who entered Monday batting .231 with 10 stolen bases in 75 games, said that he frequently encounters Giants fans wherever he goes -- including downtown San Francisco on Monday.

"They tell me, 'We miss you, Andres; we want you back. Thank you for being the [2010] World Series champs,'" he said.

Despite leaving the Giants organization, Torres said that he keeps one of his two World Series rings with him at all times (one's a replica) and frequently wears it.

"Why not?" he said.

The Giants remain a significant part of Torres' life. Despite the trade, the soon-to-be-released documentary about his struggles with ADHD is still titled "Gigante." A rough cut of the film was screened in New York on May 31. Torres believed that the final editing will be completed in time for a San Francisco premiere during the offseason.
