Tom Seaver with a slow ball.
One of the greatest openers ever, Tom Seaver is among the 3 players to have their jerseys retired by the New York Mets, and one of 2 with a Met hat on his plaque in Cooperstown (Mike Piazza). He was inducted into the Hall of Fame in 1992 with the highest percentage of votes ever (98.84%), only to be passed by Ken Griffey Jr. some years later.
