5. Sandy Koufax
8 G (7 GS), 4-3, 0.95, 57 IP, 9.6 K/9
The two-time World Series MVP may not have had a surplus of opportunities to command the postseason, but he made the most of his 57 innings of experience.
Koufax is most commemorated for his performance in the 1965 Fall Classic in which he gave up just one earned run across three starts against the Minnesota Twins.
In Game 5, the lefty struck out 10 en route to a complete game shutout and got the call once again when the Twins forced a Game 7 back at Metropolitan Stadium.
With all the momentum in favor of Minnesota, Koufax, on three days rest, pieced together a complete game shutout while striking out 10.
In three starts that series, he managed a 0.38 ERA and an opponents batting average of .160 while striking out 29 batters in 24 innings.
