This is Mark McGwire's ninth year on the Hall-of-Fame ballot. In my 2013 Hall-of-Fame ballot series, I looked at how many home runs a player in the 1970s would had to have hit to equal the value of Mark McGwire's home runs. In my 2014 Hall-of-Fame ballot series, I looked at the players whose aggregate career value - as measured by both pWins and eWins, in both levels and also over positional average and replacement level - most closely matched the career value of Mark McGwire, without regard for how that value was accumulated.

The genesis of this year's McGwire article was a traditional McGwire stat that I discovered a few years ago and is actually one of my favorite baseball factoids. In his career, Mark McGwire his 583 home runs and scored 1,167 runs. This means that he scored 583 runs which he scored on his own home runs and 584 runs which he scored via other methods.

This is the confluence of two factors. First, Mark McGwire was exceptionally good at hitting home runs (he's actually first in major-league history in home runs per at bat - or fewest at bats per home run, depending on how you calculate it). He was also, for much of his career, an exceptionally poor baserunner - and, especially toward the end of his career, frequently pinch run for.

The next table decomposes Mark McGwire's (context-neutral, teammate-adjusted) Player won-lost records by factor: batting, baserunning, and fielding.

Not surprsingly, Mark McGwire's career winning percentage for batting was very, very good, while his career winning percentage for baserunning was very, very poor. (Player won-lost records are a fan of Mark McGwire's fielding for most of his career.)

The next table shows the players with the largest gap between batting and baserunning winning percentage among players with at least 10 career batting wins and 5 career baserunning wins, among all players for whom I have calculated Player won-lost records.

Mark McGwire was not merely among the most extreme players in terms of batting vs. baserunning split. He was, in fact, the most extreme player in baseball history (of at least the past 70-80 years).

And finally, just for fun, here's the reverse table, the top 10 players whose career baserunning winning percentage most exceeds their career batting winning percentage.
