Giants sign Nady to Minor League deal

DENVER -- Continuing to stockpile position-player depth, the Giants announced the signing of outfielder Xavier Nady to a Triple-A Fresno contract Saturday.

Nady, 33, made the Washington Nationals' Opening Day roster out of Spring Training but was hampered by right wrist tendinitis. He hit .157 with three home runs and six RBIs in 40 games before Washington designated him for assignment in late June.

During his 10-year career, Nady has compiled a .271 batting average with 100 homers and 390 RBIs in 920 games. He had his best year in 2008, when he hit .305 with 25 homers and 97 RBIs for the Pirates and Yankees. But injuries have allowed Nady to play more than 100 games only once since 2009.

Sandoval showing improvement in rehab

DENVER -- Pablo Sandoval tested his strained left hamstring Saturday by taking batting practice and performing agility drills, leaving the Giants closer to determining whether the third baseman will be ready for reinstatement from the disabled list when he becomes eligible Thursday.

"I think we're getting a better idea," manager Bruce Bochy said, though he wasn't certain whether Sandoval would need a Minor League injury rehabilitation stint before rejoining the Giants.

Bochy also hasn't yet decided whether Sandoval will take practice grounders at first base, the position he was playing when he injured himself July 24 while stretching for a throw.

"Obviously, with what happened, I'm going to be a little more hesitant to put him back out there," Bochy said.

Pagan a believer in working overtime

DENVER -- Following his three-hit, four-run effort in the Giants' 16-4 rout Friday over the Colorado Rockies, Angel Pagan couldn't have been blamed for kicking back and relaxing.

Instead, he headed for the Coors Field weight room for a brief but diligent workout.

Pagan is among numerous players who include this type of extra work in their daily regimen.

"It's very important to maintain yourself through the whole year," the center fielder said Saturday. "You work so much in the offseason, but the only way it'll pay off is if you maintain it."

During the season's first half, Pagan's more likely to get his extra exercise during mornings.

"But coming down the stretch, I want to do it after the game, so I can have more rest and get ready for the game the next day," he said.

Pagan, who began this routine as a Minor Leaguer in the Mets system, emphasized that these aren't punishing workouts. He estimated that he probably lifts weights and performs strength and flexibility exercises at about 65 percent of his usual intensity.

But his objective is to perform at 100 percent in each day's game.

"It's not only for that year. It's for your whole career," said Pagan, 31. "If you want to last 10, 12, 15 years, you have to maintain your body. Because you're not getting any younger."

Bochy tabs Arias as Giants' emergency catcher

DENVER -- With Pablo Sandoval on the disabled list and Emmanuel Burriss in Triple-A, the Giants temporarily need an emergency catcher. In the wake of Friday's game, when Buster Posey left the game after eight innings and was replaced by Hector Sanchez, manager Bruce Bochy was asked Saturday which lucky Giant would have filled in behind the plate had Sanchez been sidelined.

Bochy's choice: infielder Joaquin Arias.

"He probably doesn't know it yet," Bochy jokingly said.

Arias makes sense due to his dexterity and versatility on defense. However, he has never played an inning behind the plate in 11 professional seasons.
