Probably like comparing apples and fish (as opposed to apples and oranges) but someone on this site has to advocate for Old Hoss Radbourn's 1884 season :
59-12 with 441 Ks and he literally carried his Providence team to the NL pennant... Radbourn was the pitching staff down the stretch when the Providence club took over the league lead and won the title.... and then he led them to three victories in the earliest antecedent to the World Series over the American Association NY team (he did not allow any runs).

Really he did probably did pitch the same game that Kershaw does today or even the same one that Koufax, Grove or Walter Johnson did but still....
