SCOTTSDALE, Ariz. -- John Yandle, the Giants' primary left-handed batting practice pitcher during the regular season, showed up at camp Thursday to give hitters a different look.

Switch-hitters Pablo Sandoval, Emmanuel Burriss and Andres Torres must have been the happiest Giants to see Yandle.

All three of them said that they often swing right-handed against right-handed pitchers, just to sharpen their stroke from that side. Otherwise, they'd rarely have chances to take right-handed cuts.

"You have to work more from the side you're not playing," Torres said. "If you want to make sure, you take some [right-handed] swings [against righties]."

Being a natural right-handed batter makes it easier for Burriss to maintain his stroke from that side. But, he admitted, "There aren't too many left-handed batting practice throwers, so most of my work right-handed comes off righties."

All three of them take early batting practice to create time to hit right-handed. They'll simulate left-handed pitching by adjusting the pitching machine or coaxing a coach to flip balls to them left-handed in soft-toss drills.

"It's kind of hard," Burriss said. "You can't put in the same amount of swings from both sides because you'll just wear yourself out. So you have to be pretty smart about it."

A typical switch-hitter understands that such inconveniences and challenges come with the territory. "You kind of put yourself in that position to have to be able to make adjustments," Burriss said.

Wilson gets festive; Sanchez is impressive

SCOTTSDALE, Ariz. -- Brian Wilson wore the green Thursday night. Jonathan Sanchez wore the hitters out.

Sanchez, the Giants' No. 2 starter, and Wilson, the team's closer, worked the first seven innings of San Francisco's 4-0 exhibition victory over the Los Angeles Angels.

Wilson's seventh-inning appearance prompted anticipation, given speculation that he might dye his fabled beard green in observance of St. Patrick's Day. Wilson's beard didn't change, but his footwear did. He wore shoes with green trim during his hitless inning.

Wilson said that he intends to auction off the cleats and donate the proceeds to the victims of the earthquake and tsunami in Japan. The auction is yet to be scheduled.

Asked about leaving his beard alone, Wilson said, "The cleats are as far as I'll go, as far as coloring. But it would be festive."

Sanchez became the first Giants starter to work six innings. Facing an Angels lineup that mustered two hits and featured just one projected regular, center fielder Peter Bourjos, Sanchez yielded just one hit -- Chris Pettit's first-inning single off shortstop Miguel Tejada's glove.

Asked if he had reached regular-season form, Sanchez said, "I'm not 100 percent yet, but I'm almost there."

Giants plan donations for Japan relief funds

SAN FRANCISCO -- The Giants announced that the club and the Giants Community Fund will donate $12,500 to the Northern Japan Earthquake Relief Fund established by the Japanese Cultural and Community Center of Northern California (JCCCNC).

This represents the first of several endeavors the Giants will undertake to help people affected by the tsunami and earthquake that struck the Tohoku region of northern Japan last Friday. The JCCCNC works with other organizations to ensure that 100 percent of donations are devoted to citizen relief efforts.

During the March 28 Giants-A's exhibition at AT&T Park, the Giants will have representatives available to collect monetary donations for relief and recovery efforts.

The Giants also will dedicate their annual Japanese Heritage Night game on June 3 against Colorado to the memory of the earthquake and tsunami victims. Proceeds from the sales of tickets to that will be donated to the relief efforts.
