Using baseball-reference.com, I looked up the best hitting Reds’ pitchers. This goes back through 1901. It’s fairly consistent; the best hitters show up on both career and seasonal lists, as do the worst.
To determine the single season best hitting pitcher, I had to use a minimum to eliminate pure luck, so I went with 20 plate appearances to include Micah Owings who has 21 this year.
Using OPS+, the top 25 single season leaders:
Dolf Luque in 1918 with an OPS+ of 173
Carl Mays in 1927 with an OPS+ of 168
Jim Maloney in 1961, OPS+ of 143
