Roger Clemens is the only pitcher with 300 or more victories who has not been inducted into the National Baseball Hall of Fame. Officially, baseball statistics are only kept for the National League and the American League. However, since there was no official league championship series until 1957 in the American League and 1966 in the National League, all regular season awards (including the MVP) are given equal weight in each league. Clemens' career ERA of 2.54 is the lowest among active pitchers not in the Hall of Fame. He is also first in wins with 216 and strikeouts with 7,039. Currently third on the all-time list behind Greg Maddux and Tom Seaver, Clemens could pass both of them if he continues to pitch well into his forties like other greats of the past have done. Besides Clemens, two other pitchers have won 300 games but are not in the Hall of Fame: Warren Spahn and Randy Johnson. Spahn died at the age of 70 after suffering from Alzheimer's disease for several years. Johnson is one of only three lefties not in the Hall of Fame along with Jim Bunning and John Smoltz. Bunning and Smoltz had very good careers, winning 300 games each.
