San Francisco Giant Manager Roger Craig, troubled by chest pains, was admitted Friday to Stanford Hospital, where he underwent an angioplasty to relieve blockage in his coronary arteries.
Although team doctor Will Straw said Craig could be back in uniform as early as Monday night, Giant players expressed concern.
"It's been a rough year, and that might have something to do with it," second baseman Robby Thompson said. "I've been here since '85, and it's probably the roughest year we've had."
Speculation exists that stress over Craig's first losing season as Giant manager may have contributed to the problem. The Giants were 64-76 heading into Friday night's game against San Diego.
Craig, 61, checked into the hospital after experiencing discomfort while exercising on his treadmill Friday morning. He first experienced pain Wednesday night while speaking with the media in Cincinnati.
Coach Bob Lillis served as interim manager.
