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.
