Pablo Sandoval was heard before he was seen on Wednesday morning, and that’s the way he likes it. “Every time I get in the clubhouse I’m the loudest guy,” he said. “I try to keep these guys loose.” Sandoval made his rounds on the first day of workouts at Scottsdale Stadium, chatting with younger players, yelling as he watched a clubhouse TV with veteran starters, and sitting with fellow Venezuelan Gregor Blanco for a bit. Sandoval also met with manager Bruce Bochy briefly, but their next discussion will be more important. With Evan Longoria set to be the everyday third baseman, Bochy has been waiting for the opportunity to chat with Sandoval about his role. It will be vastly reduced, with the former All-Star set to back up Longoria and occasionally Brandon Belt. At the outset, Sandoval is saying all the right things. “Those guys (Longoria and Andrew McCutchen) were faces of the franchise for their old teams,” he said. “The front office did a great job of bringing those guys here to win. (Being a backup) is a role, and you have to do everything you can to be ready.” The Giants believe Sandoval’s personality actually makes him the perfect choice for pinch-hit at-bats in big spots. His natural aggression is something Bochy likes from pinch-hitters, and Sandoval certainly has no fear. Sandoval’s energy should be an asset late in games.
