Not gonna watch an entire game, but this is some pretty compelling shit. (no homo)
It's a bunch of old guys (USA vs Canada), but they definitely take this stuff seriously.
In a 7-inning game, each team is only 'allowed' to hit 10 home runs, so they have to use them wisely, by maximizing the number of runs per homer.
These are big boys - several of them probably work out, but not to be lean or anything.
