Best lefty off all time? My vote is Koufax!

The road argument takes up a lot of the #100's and #400's posts. The benefits of Dodger Stadium are apparent, like for many other pitchers in that park during this period, the gap is often astronomical. His total home/road splits:

1955
Home 2.25
Away 4.08

1956
Home 7.50
Away 3.76

1957
Home 3.70
Away 4.10

1958
Home 3.70
Away 4.10

1959
Home 2.71
Away 5.50

1960
Home 5.27
Away 3.00

1961
Home 4.22
Away 2.77

1962
Home 1.75
Away 3.53

1963
Home 1.38
Away 2.31

1964
Home 0.85
Away 2.93

1965
Home 1.38
Away 2.72


1966
Home 1.52
Away 1.96


Once the Dodgers move to Dodger Stadium in 1962, Koufax becomes Koufax. Doesn't hurt it was also an expansion year. After Koufax becomes Koufax, his away ERA's, relative to the league, are fairly similar to what they were in 1960 and 1961. His 1966 Away performance is amazing even in the low run context of 1966, but other than that the gap is huge the other years of his greatness.
