Best non all-star baseball player ever

[Sooga]

Who's the best player in baseball history to have not played in the all-star game? Obviously, players who were active during an era when there was no all-star game in existence do not count.

I don't know enough about older players to make any guesses, but the only names that pop into my head now are Eric Chavez (who is only 27 and I'm sure will be an all-star eventually), and Tim Salmon, who I only know never was an all-star because I follow the Angels. Any other picks?
