once every 432 PAs or so against RHP, Phil will get an HR on his own card -- on a 1-8 roll, followed by a 1 on the 20-side die
Technically, since Gosselin was playing home, the probability of hitting a homerun on his own card was slightly better than 1/432
(a certain percentage of outs are re-rolled so that the overall batting average is increase by 1%, or .010 out of 1.000)
