Cain excited for '14 rotation, follows Hot Stove

SCOTTSDALE, Ariz. -- Matt Cain, Madison Bumgarner, Jeremy Affeldt and Javier Lopez will be among the more experienced Giants throwing off bullpen mounds Saturday as pitchers begin working toward season-opening shape.

Tim Hudson, Tim Lincecum, Sergio Romo and Ryan Vogelsong will be among the pitchers taking their first turns Sunday.

Naturally, San Francisco's prospects will draw plenty of attention. One pitcher guaranteed to be scrutinized Saturday is left-handed starter Edwin Escobar, whom general manager Brian Sabean mentioned as having an outside chance to ascend all the way to the Majors this year. Sunday's contingent will include right-handed starter Kyle Crick, the organization's No. 1 prospect, and reliever Derek Law, who enjoyed an outstanding 2013 season in the Minors and the Arizona Fall League.

Sanchez shapes up for Spring Training action

ARI@SF: Giants score first on Sanchez's RBI single

SCOTTSDALE, Ariz. -- Hector Sanchez's sleek new look captured the optimism that accompanies the start of Spring Training.

Sanchez, the Giants' backup catcher, showed up at the team's Scottsdale Stadium clubhouse Friday weighing nearly 20 pounds less than he did last year, when he was listed at 234 pounds. He was partly driven by suggestions from management about getting in better shape. Sanchez also simply wanted to feel better.

"I feel like my energy's at a different level," said Sanchez, who hit .248 in 63 games last year after batting .280 in 74 games as a rookie during San Francisco's World Series-winning season of 2012.

Sanchez, 24, also wanted to avoid shuttling back and forth between Triple-A Fresno and the Majors as he did last season while enduring a right shoulder injury.

"Last year was a learning experience about how I had to be in shape," Sanchez said. "I had to be ready."

Said manager Bruce Bochy, "It's nice to see Hector take that next step and show more ownership of coming into camp in good shape."

Pitchers and catchers officially reported to camp and underwent physical examinations Friday, though dozens of them -- as well as a handful of position players -- already have begun informal workouts at the stadium. Batterymates will open workouts Saturday. Position players are due to report Tuesday, one day before the first full-squad workout.

Veteran Casilla's reporting delayed by visa issue

COL@SF: Casilla secures his second save, Giants' win

SCOTTSDALE, Ariz. -- Maybe it's an oddity; maybe it's just an example of clerical red tape. But for some reason, visa problems are delaying veteran right-hander Santiago Casilla's arrival in camp, while his brother, rookie right-hander Jose, has reported.

Giants manager Bruce Bochy offered no explanation for why Jose, nearly nine years younger than Santiago, avoided complications.

Bochy said the Giants have sent the daily workout plan to Santiago Casilla and left-hander Jose De Paula, who's also stuck in the Dominican Republic due to visa issues. Bochy said they can maintain their conditioning and do their throwing at the Giants' baseball academy there.
