When I was writing yesterday about Mike Marshall passing away, and talking about his extraordinary workload he was able to handle out of the pen for a few years with the Montreal Expos and Los Angeles Dodgers, I went to look at the list of the all time single season leaders for pitchers in games. I thought he may have had the top two or three seasons in number of games pitched.
Marshall did not, in fact, have the top two or three, but he did have three of the top nine all time.
