Bochy: No talks of position switch for Posey

WASHINGTON -- If it's late in the season, it's time for manager Bruce Bochy to discuss Buster Posey's future as a catcher.

For now, asking Posey to switch positions to preserve his offensive prowess isn't on the Giants' agenda. But various factors could prompt a change in circumstances. Among them:

• The differences in Posey's production. He has been more prolific this year as a first baseman, batting .385 with a .961 OPS, compared with .265 and .749 as a catcher. However, he has compiled his numbers at first base amid a relatively small sample size -- 22 starts, compared to 88 behind the plate.

• Strengthening the lineup overall. Andrew Susac has impressed the organization since his promotion from Triple-A Fresno. And if Hector Sanchez ever shakes his concussion issues, he possesses tremendous potential value as a 24-year-old switch-hitting catcher.

• Posey's health. The stiff right hip that forced him to rest Wednesday in Chicago is nothing new. And as a catcher, the 27-year-old is subject to much more physical erosion than other position players.

Bochy said that he likes having Susac and, when healthy, Sanchez available to spell Posey and "lighten the load" on him. But Bochy insisted that this hasn't fed whatever urge the Giants might have to move Posey to first base. Because if Posey ever does change positions, first base will be his new home.

"If sometime down the road he'll get out from behind the plate, I can't answer that," Bochy said. "Right now, it's not [being] discussed. But I will say that it's nice to have options."

Peavy impressed with Lincecum's accomplishments

WASHINGTON -- With a victory Saturday over the Nationals, Giants right-hander Tim Lincecum would become the fifth pitcher to win 100 games with the club since the franchise moved west in 1958.

The others all distinguished themselves to varying degrees. Juan Marichal (238 wins as a Giant) is a Hall of Famer who's regarded as one of the finest pitchers of his era. Gaylord Perry (134), another Hall of Famer, tacked on 180 more wins after the ill-advised trade that sent him to Cleveland before the 1972 season. Kirk Rueter (105) remains the winningest left-hander in San Francisco history. And Mike McCormick (107) became the Giants' first Cy Young Award winner in 1967.

Lincecum's resume measures up to those of his predecessors. He has won two Cy Young Awards, thrown two no-hitters, made four All-Star teams and built a postseason record that's exceeded in franchise history only by Christy Mathewson.

Discussing win No. 100 during Spring Training, Lincecum said, "I'll be proud of it when I get there. That's not something I've ever actually shot for."

One Giant who understands the significance of reaching triple digits in victories is Jake Peavy, who has amassed a 135-110 record in 13 big league seasons.

"I don't think it's really symbolic of anything," Peavy said Friday. "It's a round number is what it comes down to."

Peavy added that since fewer starting pitchers work deep into games and thus are less responsible for their decisions, the impact of win totals has ebbed.

"There are so many better ways to judge how good a pitcher is," Peavy said.

Peavy pointed out that he won the Cy Young Award with a 19-6 record and a 2.54 ERA in 2007 for San Diego, yet finished 10-11 the following year despite posting a similar ERA (2.85).

That said, Peavy affirmed that Lincecum should feel rewarded once he reaches the century mark.

"When anybody who understands how hard it is to win a Major League game sees those 100 wins, there's a ton of respect from your peers when you see guys start to rack up wins like Tim has," Peavy said.

Prospect Blackburn fires seven shutout innings

Last Saturday, Giants prospect Clayton Blackburn made what might have been the best start of his career, striking out a career-high 11 batters in eight scoreless innings. He came close to replicating it Friday, throwing seven scoreless innings to lead Double-A Richmond to a 3-0 victory over Bowie.

Blackburn, the Giants' No. 7 prospect, struck out nine batters, walked two and scattered six hits in the effort. He threw 97 pitches and extended his scoreless-innings streak to 15.

The Baysox recorded five hits and one walk in the first three innings, but Blackburn was able to keep them off the scoreboard. He then all but silenced their offense in the final four innings, striking out seven batters.

Blackburn earned his first victory since July 4, when he returned from the disabled list to throw five scoreless innings in Game 2 of a doubleheader against Reading. He had been sidelined since May 19 by a strained lat muscle in his right side.

In 16 starts for the Flying Squirrels this season, Blackburn is 4-5 with a 2.64 ERA. He has struck out 77 batters and walked 19 in 85 1/3 innings.
