Pitchers batting since 1901. Except for Babe Ruth, they suck.

Good hitting pitchers is an oxymoron. What a great word, even if I had to look it up to verify its meaning.

Using the ad hoc query function (play index) at baseball-reference.com:

238 pitcher seasons found. Here are the tops with OPS+ at least 150:

Five of the 15 are post World War II (after 1945). The most recent and the only one since Larsen in 1958: Micah Owings 2007, who in 219 plate appearances (PA) through 2012 had career OPS+ 105.

Brickyard Kennedy in 1903 is the only one with zero home runs (HR) among the top 15 in OPS+ for a season. Wes Ferrell hit 9 HR, the record for pitchers; Newcombe hit 7 HR; four HR for Ruth, Ruffing, Larsen, Owings.

Top 14 pitchers in hitting HR in a season, at least six:

Finally, most career HR. In order to include Wes Ferrell (season and career record holder), the percent of career games at pitcher was reduced from 75% to 66%.

https://www.baseball-reference.com/players/f/ferrewe01-field.shtml

Wes Ferrell pinch hit (PH) 162 times and in 1933 played left field in 13 games but hit no HR as LF. In five games he hit two HR. In 1931 when Ferrell hit the pitcher's record of 9 HR, Ferrell hit all 9 HR as a pitcher. Ferrell hit only one PH HR and it was a three run walk-off in 1935; his next HR was the next day and it was also a walk-off game winner. His only other walk-off was the second of two in a 1934 game. He also hit one IPHR. His HR log as a batter:
