SCOTTSDALE, Ariz. (AP) -- San Francisco Giants manager Bruce Bochy is ''doing great'' and is expected to be released from the hospital Friday, a day after a heart procedure to insert two stents.

Brett Bochy, a pitcher with the team at spring training, said he visited his 59-year-old father at Scottsdale Healthcare Medical Center on Thursday and Friday morning before going to the clubhouse. The hospital is across the street from where the Giants work out.

''He's doing great,'' Brett Bochy said. ''It's a little scary to go to the hospital, but he's in good hands here. They noticed something after his physical early so it was caught early, and he's feeling great now.''

The Giants said Thursday the team's medical staff had been monitoring the manager's heart after he experienced discomfort following a physical exam Wednesday, when the World Series champions reported to spring training.

''He couldn't be in better spirits,'' Brett Bochy said. ''He's ready to get back out. He wants to be back out (on the field) today, but they're keeping him out just for precautionary reasons.''

Bruce Bochy addressed the media on the first workout day for pitchers and catchers Thursday and joked with reporters, never revealing anything about his physical.

Bochy, who turns 60 in April, has led the Giants to three World Series titles in the past five seasons - 2010, 2012 and last year. He came to the Giants from the San Diego Padres before the 2007 season and has spent 20 years as a manager.

Brett Bochy said his father doesn't have a history of heart problems, but the manager's father died of a heart attack and Bruce Bochy has always been monitored because of that.

''It's scary anytime you hear anything involving someone's heart,'' Giants catcher Buster Posey said. ''Happy to hear that he's doing well.''
