Longtime New York Yankees closer Mariano Rivera became the first player to ever be voted unanimously into the Baseball Hall of Fame Tuesday, joining former Yankees and Baltimore Orioles ace Mike Mussina, the late Toronto Blue Jays and Philadelphia Phillies pitcher Roy Halladay and former Seattle Mariners designated hitter Edgar Martinez. Rivera, who holds the record for most saves all-time and won five World Series championships, made it into Cooperstown on his first try as did Halladay, who died in a 2017 plane crash.
