BREAKING NEWS: George Steinbrenner, owner of New York Yankees, has died in Tampa at age of 80 after heart attack.

George Steinbrenner, a towering and intimidating figure who dominated the New York sports scene for 35 years, winning 11 American League pennants and seven world championships as owner of the Yankees, in and around two suspensions from baseball and multiple feuds and firings, died Tuesday morning in Tampa after suffering a massive heart attack. He was 80.

"The Boss" - as he was so aptly named by Daily News columnist Mike Lupica, his longtime antagonist - died at around 6:30 a.m. He had been suffering from failing health, the result of a series of strokes, for the past few years.
