George Steinbrenner, owner of the New York Yankees since 1973, passes away from a heart attack at his home in Tampa, FL. Steinbrenner restored the Yankees to greatness during his ownership, spent lavishly on free agents, fired managers and front office personnel at a sometimes dizzying pace, but saw the team win seven World Series titles. He had relinquished the team’s operations to his son Hal Steinbrenner as his health deteriorated badly in 2008.
