Appearing in his first major league game at the age of 29 in 1952, Wilhelm would go on to have a 21 year career. He was the first pitcher to ever appear in over 1000 games. He still holds the record for most relief wins with 124 and he was the first pitcher to save over 200 games. His career 2.52 ERA is the lowest in the last 90 years. Wilhelm also tossed a no hitter in his role as an occasional starter in 1958. His main pitch, the knuckleball, was said to have the best knuckler ever. He created the position of closer and appropriately was the first relief pitcher voted into the Hall of Fame.
Wilhelm hit a home run in his first major league plate appearance against the New York Giants, over the short right field fence at the Polo Grounds. He played a total of 1070 games and never hit another one.
