Hall of fame pitcher Phil Niekro has passed away at 81 years old.
Niekro died Saturday night in his sleep after a long bout with cancer. This announced by the Atlanta Braves on Sunday.
Niekro was most known for his signature knuckleball, a pitch so unpredictable that it fooled batters - and fellow pitchers - for generations.
He won 318 games in his 24 season career which includes 21 years with the Milwaukee/Atlanta Braves and two with the New York Yankees in 1984 through 1985 before retiring in 1987 at age 48 making him the oldest regular player in league history.
His 121 wins after the age of 40 is an MLB record.
Niekro would go on to become the manager of the women's Colorado Silver Bullets from 1994-1997.
In '97 he would make his way to Cooperstown to be inducted into the National Baseball Hall of Fame. He served on the Museum’s Board of Directors since 2009.
He is now the seventh member that the Baseball Hall has lost this year.
