Mariano Rivera, a 20-year-old fringe prospect from Panama, signed with the New York Yankees on February 17, 1990, for a $3,000 bonus. This was the first step on his journey to becoming a Hall of Fame closer, as he went on to save a record 652 games, earn 13 All-Star selections, and win 5 World Series titles with the Yankees.

Why it matters

Rivera's signing with the Yankees marked the beginning of one of the most dominant pitching careers in MLB history. As a closer, he perfected the cut fastball and developed a virtually perfect closer's mentality, leading the Yankees to sustained success in the late 1990s and 2000s.

The details

Rivera was initially an outfielder playing for a local amateur team in Panama before being asked to pitch in a game in 1989, where he found his calling. Yankees scout Herb Raybourn convinced Rivera to try professional baseball, and the Yankees sent him to their rookie ball team in Florida, where he dominated younger competition with his live fastball. An arm injury in 1992 nearly derailed his career, but Rivera bounced back and by 1995 his fastball had jumped from 91 mph to 96 mph, earning him a promotion to the big leagues that year.

  • On February 17, 1990, Mariano Rivera signed an amateur free agent contract with the New York Yankees for a $3,000 bonus.
  • In 1992, an arm injury led the Yankees to leave Rivera unprotected in that year's expansion draft, but neither the Rockies nor the Marlins were interested.
  • In the middle of the 1997 season, Rivera perfected the cut fastball that would define the rest of his career.
