Major League Baseball umpire Wally Bell died of an apparent heart attack Monday, just a week after working the NLDS between the Pittsburgh Pirates and St. Louis Cardinals.

The commissioner's office said the 48-year-old Bell died in his home state of Ohio.

He had not been feeling well over the weekend and had been scheduled to see doctors later Monday at the Cleveland Clinic.

Bell had quintuple bypass surgery on Feb. 18, 1999, that left him with an 8-inch scar down the middle of his chest. His father survived two heart attacks before he died.
