Game 277 | May 2, 1980 | George Steinbrenner
A "close personal friend" of Sid Hartman's, Yankee owner Steinbrenner traced his career from graduate assistant to Ohio State's legendary Woody Hayes to Great Lakes shipping magnate to his decision to purchase the Yankees for $10 million in 1973. Under his ownership, the Yankees, floundering at the time of his purchase, won 10 American League pennants and six World Series titles over the next 25 years.

Game 480 | June 8, 1995 | George Steinbrenner
With the New York Yankees in town to play the Twins, Steinbrenner accepted an invitation to re-visit Dunkers. His team was coming back from a long rebuilding process with young players such as Derek Jeter, Jorge Posada, Bernie Williams and Andy Pettitte joining the likes of Don Mattingly, Wade Boggs, Paul O'Neill and Jack McDowell. The team reached the playoffs in 1995 and won the World Series a year later.
