Roberto 'Bobby' Bonilla is a former Major League Baseball third baseman and outfielder who played from 1986 to 2001. A six-time All-Star, he was a key member of the Pittsburgh Pirates in the early 1990s and won the 1997 World Series with the Florida Marlins. Bonilla was a formidable switch-hitter known for his power during his 16-season career. He remains a notable figure in sports culture due to his unique deferred-payment contract with the New York Mets, which results in a yearly payment on July 1st, a date widely known as 'Bobby Bonilla Day'.
