SCOTTSDALE, Ariz. — The season hasn’t begun, but Pablo Sandoval already is compiling some impressive statistics.

At his long-awaited physical exam and official weigh-in Friday, Sandoval tipped the scales at 240 pounds, according to Ethan Banning of Triple Threat Performance, which coordinated his offseason conditioning regimen.

Sandoval weighed 278 pounds at the end of last season. He also reduced his body fat measurement from 30 percent to 19 percent, Banning said.

“That’s not Mr. Universe, but it’s a long way from where he was,” Banning said.

Banning estimated that the 5-foot-11 Sandoval gained nearly seven pounds of muscle on the highly disciplined nutrition and training plan, so his total fat loss was closer to 45 pounds.

Sandoval said he was happy with the result. So is Giants manager Bruce Bochy.

“I don’t need to look at a scale to see how hard he’s worked and where he’s at,” Bochy said. “It’s pretty evident he’s done a lot this offseason to get in the condition he needs to be in. I’m happy. We’re all happy.”

Backup catcher Eli Whiteside will miss Saturday’s first full squad workout, and likely a few days more, while allowing inflammation in his right elbow to subside. An MRI exam and X-ray found fluid in the elbow but no structural issues; Whiteside said he expected to be fine after some rest and a few days of anti-inflammatory medication. Chris Stewart, a non-roster invitee, is the only other catcher in camp with any big league service time.

Bochy said he anticipates catcher Buster Posey will start upward of 135 games this season and won’t be used at first base often. “If any,” Bochy said. “When he gets a day off, I want him to get a complete day off.”

Closer Brian Wilson played catch for 10 minutes off flat ground and said his stiff back was improved, touching his toes to prove it for reporters. He plans to take part in Saturday’s workout. “Nobody runs in cleats in the offseason,” Wilson said. “It happens in spring training. It’s just part of being an athlete.”

Wilson, who drove an unmarked police cruiser earlier in the week, switched to a cream-colored classic Cadillac low rider. He’s driven three different cars to the ballpark in three days.
