Stanton and Judge: 2017 Home Run Proficiency relative to league among all time leaders.

Giancarlo Stanton and Aaron Judge led their respective "leagues" in 2017 in home runs with 59 and 52 respectively. Rather than simply looking at the totals, let's see where they fit in among other sluggers all time. Read this for context, then the results for Stanton and Judge below.

Home Run Proficiency relative to League. Thursday, December 13, 2012

Babe Ruth dominates as do other batters of the 1920s and 1930s. Ruth took spots 1 through 9, 11, 13. Of the top 19 spots, the only one later: Hank Greenberg 1946: 4.43 time more proficient at hitting home runs (HR) than the other batters in his league that season. Best position after Greenberg: Mike Schmidt 21 (1980).

Schmidt hit 48 home runs in 1980, 3.81 times better than non-DH NL.

Judge has already been examined:

Judge came out a modest 1.54 times more proficient. In the study below that was done for seasons through 2012, Judge would be number 159 of the 166 seasons. The only 50 homer season lower in that group was number 162, Brady Anderson: 50 homers in 1996, 1.51 times more proficient than AL.

Stanton's 59 tied Babe Ruth for the ninth most home runs hit in a season. The only players with more than 59: Barry Bonds, Mark McGwire, Sammy Sosa, Roger Maris and Ruth himself, who hit 60 in 1927 breaking his 1921 record of 59.

Maris has the least ...

Yankee teammate Mickey Mantle was 2.96 times better than the AL in 1961 with his 54 home runs in 540 at bats.

Stanton was 1.82 times better than the NL in 2017, a "league" which requires the pitcher to bat. That would reduce the NL Home Run Proficiency and make Stanton's number better than in a DH "league". Once again, Judge was 1.54 better than AL in 2017.

Ranked 147 among the 166 seasons in the 2012 study was Luis Gonzalez of NL Arizona at 1.82 in 2001. Gonzalez hit 57 home runs but was third behind Barry Bonds 73 (3.67 better than NL) and Sammy Sosa 64. In that study the season right behind Gonzalez was Ken Griffey: 1998, 56 homers, 1.816.
