Bochy rejoined the World Series champions Sunday, three days after having a heart procedure.
"I couldn't feel any better," Bochy said. "I am grateful for the doctors and want to thank all the well-wishers who sent me messages."
The 59-year-old manager had two stents put near his heart Thursday night.
Doctors had told Bochy to stay away from the ballpark for a few days. He slipped back into his office Saturday.
Bochy said he didn't feel good for much of the off-season.
After he took his annual spring physical Wednesday, Bochy followed the suggestion of team physician Robert Murray and team trainer Dave Groeschner and headed to a medical center.
"I go in and the next thing I know, I'm getting stents put in," he said.
Bochy has guided the Giants to three World Series titles and is starting his 21st season as a big league manager.
Bochy won't be allowed to work out for a few weeks.
Dan Haren is trying to make it work
For Miami Marlins pitcher Dan Haren, the relocation from Southern California to South Florida will take some getting used to.
The 34-year-old right-hander reported to his new team this week after contemplating retirement, but he made it clear Sunday he still feels the tug of faraway family. His wife and two children are in Los Angeles.
The well-traveled Haren was happy to pitch for the Dodgers last season. He raised the possibility of retirement in November, hoping to dissuade East Coast teams from trading for him.
But he was due to be paid $10 million this season and said the big salary was a factor in deciding to join the Marlins.
"It's hard to leave that much money on the table," he said. "Can I walk away from it? That was definitely a factor."
Of his talk of retirement, Haren said part of it was a ploy.
"There are ways you can maneuver the media to help you stay in a certain place maybe," he said. "I was trying to leverage things."
New York Yankees right-hander Masahiro Tanaka said he felt fine after throwing 34 pitches during his second bullpen session. Tanaka sat out 2 1/2 months last season while rehabilitating a partially torn ligament in his right elbow. ... The glove Jeffrey Maier used to pull Derek Jeter's home run over the wall during the 1996 American League Championship Series against Baltimore has been sold at auction for $22,705. The auction house said the glove was purchased Saturday by an anonymous collector.
