It wasn’t until 1919 that Babe began his transition into a hitter, with 17 games pitching and 130 games hitting that year. In the four and a half seasons that Babe devoted to pitching, he amassed the following statistics:

ERA – Earned Run Average (2.28 career): #1 in ERA in the American League (AL) in 1916.
15th overall for career ERA.

Wins (65 career): Top 3 in the AL in 2 of his 5 full seasons as a pitcher.
Won the most games of any left-handed pitcher in the Majors from 1915-17.

Win/Loss% (.671 career): 12th on the list for best career win/loss percentage.

Strikeouts: Top 5 in the AL in 2 of his 5 full seasons as a pitcher.

Shutouts: #1 in the AL in 1916.

In Babe Ruth’s 1916 season as a pitcher, his record was 23 Wins and 170 Strikeouts, with a 1.75 ERA, 9 Shutouts and 23 Complete Games

In the 1916 World Series between the Red Sox and Brooklyn Robins (eventually Dodgers), Ruth took on Sherry Smith in what would become one of the biggest pitching match-ups in history. The game was tied 1-1 through 14 innings until the Red Sox finally scored and won the game. Both Ruth and Sherry Smith pitched the entire game, which is still the longest World Series game ever played.
