Home Run Proficiency Career

Babe Ruth
In 1895, the year Babe Ruth was born, 6' 3", 220 pound Roger Connor at age 37 hit 8 home runs (HR) for St. Louis in the National League (NL) and passed 5' 11", 175 pound Harry Stovey, the first batter to hit 100 HR, for the most HR in a career.  Connor finished the season with 126, four more than Stovey.  Connor retired after playing 22 games in 1897 with 138 HR, a record he held until Ruth hit 59 HR in 1921 and finished that season with 162 HR.

Our evaluation of HR hitting has remained primitive to the present.  The simple method that I have been using recently is a big improvement over totals.  Here are the top four HR hitters based on count:

Rk Player HR From To Age G PA AB R H 2B 3B RBI BB IBB SO HBP SH SF GDP SB CS BA OBP SLG OPS Pos Tm
1 Barry Bonds 762 1986 2007 21-42 2986 12606 9847 2227 2935 601 77 1996 2558 688 1539 106 4 91 165 514 141 .298 .444 .607 1.051 *78/D9 PIT-SFG
2 Hank Aaron 755 1954 1976 20-42 3298 13941 12364 2174 3771 624 98 2297 1402 293 1383 32 21 121 328 240 73 .305 .374 .555 .928 *9783D/45 MLN-ATL-MIL
3 Babe Ruth 714 1914 1935 19-40 2503 10620 8399 2174 2873 506 136 2213 2062 1330 43 113 2 123 117 .342 .474 .690 1.164 971/83 BOS-NYY-BSN

We all know these numbers: 762, 755, 714, 660.  But how many of us know these:
 9,847
12,364
 8,399
10,881

Those are the at bats (AB).  Using the two together we get a much better insight into the relative achievements.  Even better insight is gained with my home run proficiency method, which simply subtracts the player's HR and AB from the league total and divides league HR by AB to get the league HR rate for all the other batters.

(P-(L-P))/((L-P)
In this equation each letter represents (HR/AB) for either the player or the league minus the player.  The result is the number of times the player's HR rate is better than all the other batters in that league that season.

Season numbers have been in recent posts, labeled X in associated spreadsheets.  This post takes that season data and aggregates for a career number (Y) weighted of course by AB per season.  For data through 2011 there are 771 batters with at least 100 career HR.  Sorted by Y (career home run proficiency), number one was Babe Ruth, number 771 was Wade Boggs.

Click link to view data.  There are tabs for :
- top 50 or so
- bottom 50 or so
- 493 HR or 50 HR in a season

- Retired 1903-1928
- Retired 1929-1953
- Retired 1954-1979
- Retired 1980-1999
- Active after 1999

As was seen in the season data there is a clear trend toward more HR hitting by all batters, which reduces the proficiency factor in more recent decades.

First let's see where the top four ranked among all 771 batters with at least 100 career HR.

1. Ruth 7.8 times more proficient than the other batters when he played
30. Bonds 1.84
41. Aaron 1.64
53. Mays 1.5

Note: In a recent post I showed that Mays was a better HR hitter than Aaron by examining their common peak seasons (1954-1968) on the road but not in each others parks.  My guess is that Aaron has an edge for their entire careers because:
- Mays missed two seasons in the Army
- Aaron got a late career boost playing his home games in Atlanta (1966-1974)
- Aaron experienced an inexplicable surge in his HR proficiency at an age when sluggers generally decline: age 37 career best, age 39 second best.

Top 11 of the 771 includes three guys named Williams:

Now let's see the career rank for modern season HR record holders.

1. Ruth 7.8
2. Gavvy Cravath 4.56
18. Mark McGwire 2.3
30. Bonds 1.84
68. Sammy Sosa 1.37; He held the record briefly during the season, so what the heck, you're curious, right?
135. Roger Maris 1.01

493 HR or 50 HR in a season (43 batters):
