Forgetting about the H/9 IP numbers for now, I was curious to find out which pitcher gave up more than two hundred hits in the fewest innings pitched. I looked at the years 1901-2007 in order to avoid the myriad rule changes and schedule havoc of the nineteenth century. Twenty-six pitchers since 1901 have given up over 200 hits in less than 160 innings. Here they are, for your reading pleasure:
Unsurprisingly, almost all of these seasons took place during the two most batter-friendly eras in baseball history: the 1920's-1930's and the late 1990's through today.
I didn't list them all, obviously, but a pitcher gave up 200+ hits in less than 200 IP 701 times since 1901. There have been 4,588 total 200+ hits allowed seasons since the AL came into existence that year.
