Frandsen calls SF home, but happy with Phillies

SAN FRANCISCO -- Part of Kevin Frandsen's heart, which might be composed of horsehide and held together by red stitching, will always belong to the Giants organization.

"It's home," said Frandsen, now a Philadelphia Phillies reserve who's in the middle of his first trip to AT&T Park as a visiting player. "This is where you were born as a professional baseball player."

Frandsen's loyalty to the Giants extends only so far. Once Frandsen shows up at the ballpark, everything changes for the San Jose native, who grew up rooting for the Giants, was drafted by the Giants and accepted the club's support as his late brother DJ's fight against cancer ended.

"You flip a switch," Frandsen said Tuesday, "and you just want to beat them."

Frandsen, who hit .240 in 174 games for the Giants from 2006-09, has channeled much of his competitive spirit into pinch-hitting. He entered Tuesday batting .364 (4-for-11) in that role. He has started in only three of Philadelphia's 34 games. That's what happens to a reserve infielder playing behind All-Stars Ryan Howard, Chase Utley, Jimmy Rollins and Michael Young. But though that quartet keeps Frandsen on the bench more often than not, he relishes being their teammate.

"You've got professionals, guys who have done it, guys who have won and had huge success," he said.

That attitude has helped Frandsen, who turns 31 on May 24, find a second home in Philadelphia. As much as Frandsen reveled in being a Giant, some players tired of his ceaseless intensity.

"I wasn't always accepted by the veterans," he said. "[Due to] my passion for the game, I was always up and high on energy all the time. They didn't really like it all the time. Now, it's accepted here. That's awesome."

Giants activate Mijares, option Machi

SAN FRANCISCO -- Opting for an adequately stocked bench over above-average pitching depth, the Giants activated left-hander Jose Mijares from the restricted list Tuesday and optioned right-hander Jean Machi to Triple-A Fresno.

Machi excelled during his nine-game Giants stint, recording a 1.74 ERA. But keeping him would have expanded the pitching staff to 13 while leaving San Francisco a reserve short.

Manager Bruce Bochy acknowledged that he and the club's braintrust discussed the possibility of trimming a reserve to keep Machi on the staff. Bochy pointed out that making that kind of move remained within the realm of possibility.

"We always have that ability, if we think we're in a box and need another arm, [to] make that move at another time," he said.

And when the Giants make that move, Machi has a good chance to return.

"It's nice to have a guy down there who we know can pitch here," Bochy said. "It gives us that confidence to call him up anytime."

Mourning his grandmother, who suffered a fatal heart attack, Mijares went on bereavement leave after the April 28 game at San Diego, where he made his last appearance. He was moved to the restricted list Monday when the Giants determined that he would not arrive at AT&T Park in time for that night's game.

Bochy wasn't concerned about Mijares' inactivity, which included not throwing while he was on leave in Venezuela. Bochy said that Mijares probably could regain some sharpness by performing "touch and feel" drills, which require a pitcher to throw at 60 percent of his usual intensity.
