Perspective on Sosa's 500 HR

Measuring the greats against their peers

By Tangotiger

The 500 HR club has come into question. Because it is apparently easier to hit HR now, perhaps the line should be moved up to account for this. First of all, is this so? And secondly, how can we do it?

Here is a table of the 10th best HR totals, for selected years.

Year HR-10
1920 11
1930 35
1940 25
1950 31
1960 31
1970 36
1980 29
1990 32
2000 42

We see that some years it's easier for the big boppers to get many HR, and other years it's harder. And these days, it's much easier.

Here's where we have some fun, and I'll use Sammy as my example to go through it step-by-step. In 2002, the average hitter had 614 AB, and the 10th best HR total was 39. Sammy Sosa had 556 AB. Since Sammy had 90% of the AB of the average hitter, we will reduce that 39 HR figure by 10%. The new baseline HR figure, for Sammy, is 35 HR. We do this for every year that Sammy played. Here's how Sammy did, as well as his baseline peer.

Year AB HR HR-10 Diff Rate
1989 183 4 9 -5 44
1990 532 15 28 -13 54
1991 316 10 16 -6 63
1992 262 8 14 -6 57
1993 598 33 35 -2 94
1994 426 25 21 4 119
1995 564 36 32 4 113
1996 498 40 34 6 118
1997 642 36 42 -6 86
1998 643 66 46 20 143
1999 625 63 42 21 150
2000 604 50 41 9 122
2001 577 64 38 26 168
2002 556 49 35 14 140
Total 7026 499 433 66 115

Sammy Sosa has 66 HR more (and 15% more) than the 10th best HR hitter of each year, while Sosa was playing.

Without any more delay, here are all players, since 1919 with 3000 AB, with a career HR total that is at least equal to his peer-baseline

There are many problems with this perspective: (1) the more hitters you have, the higher the baseline level, (2) the HR figures for the league used gross figures and were not AB adjusted, (3) using one spot (the 10th highest) can cause huge swings, (4) a player stretching out his career will start to lose "points" as he gets further and further away from that top 10 spot. And I'm sure there are many, many more. But, I did this for fun more than anything, and I hope you enjoyed it.
