Best lefty off all time? My vote is Koufax!

Koufax led the league in ERA 5 times. Pretty impressive. Grove led the league in ERA 9 times. More impressive.

You can't win these arguments, Koufax vs Grove:
Best season - Grove's 1931 is insane. The 3 guys to win 30 games since 1920 are Grove (31 in 1931), Dean (30 in 1934), and McLain (31 in 1968.) Despite Grove and Dean doing it in a 154 game season, and players since 1961 having 8 more games, it hasn't been done in the last 50+ years.

Best run of 6 consecutive seasons: Grove, see above.

Career:
ERA titles: Koufax 5, Grove 9
Wins: Koufax 165, Grove 300
Win percentage: Koufax 65%, Grove 68% (highest among 300 game winners and eighth best overall).

Short term (one season), Grove.
Best years (6 season run), Grove.
Career, Grove.

We remember Koufax. Many of us saw him in his prime. He is a very popular player and fellow.

Grove was better, period.

This is your opinion and I disagree with it. Dominating a weak pitching era doesn't make someone better than a pitcher who dominates one of the strongest pitching eras. Wins are not a good metric to use to compare pitchers. I have presented evidence in this thread that Koufax lacked the run support that Grove received. Koufax should have won 30+ games both in 1963 and 1966. Grove's 31 wins were a matter of luck. He won 4 games where he gave up 4+ runs. That is a poor pitching performance under any circumstance, but the A's powerful offense bailed him out. He also won 4 in relief including a 3 inning relief appearance where the A's gave him the lead in the tenth and Grove blew it only to have the A's to score twice in eleventh.

Koufax had 2 or 3 seasons better than Grove's best. Koufax's 6 year run from 1961-1966 was better than Grove's, ERA, WHIP, FIP, K/9, no hitters, etc. Even Koufax's career numbers are better including counting stats like shutouts and strikeouts despite Koufax retiring at 30. Grove just pitched for stronger offensive team over a long period of time resulting in more wins. These are just opinions, but I don't judge a pitcher by wins.
