Baseball great, Phil Niekro, is a former MLB pitcher for the Atlanta Braves and member of the Baseball Hall of Fame. With 318 career victories, Niekro is the most successful knuckleball pitcher of all time. He was also an excellent fielder, winning the National League Gold Glove Award five times. Together with his brother Joe, the Niekro brothers are the winningest brother combination in baseball history, with 539 wins combined. Phil Niekro's 121 career victories after the age of 40 is a major league record, and his longevity is attributed to the knuckleball, which, while a difficult pitch for pitchers to master, is easy on the arm and difficult for batters to hit.
