Death of Dave Niehaus
Long-time broadcaster Dave Niehaus suffered a myocardial infarction (heart attack) at his Bellevue, Washington, home on November 10, 2010, and died at age 75 while preparing to barbecue some ribs on his deck. Heart problems had forced Niehaus to undergo two angioplasties in 1996, causing him to give up smoking and change his diet. He is survived by his wife, three children, and six grandchildren. The team wore patches on their jerseys in commemoration of Niehaus during the 2011 season.
