Prior to my last two picks (which are coming up soon, I hope), my Yaz/Piazza/McGwire team has 400 real-life HRs in 4922 ABs, a rate of 8.1%, or roughly 45 HRs per 550 ABs. Of course, that includes bench guys since I can't start all four Piazzas or all four McGwires. When I add my last two starting batters, this HR rate will drop to about 7.1% or 39 HRs per 550 ABs.
