Home and away

Over at The Usual Suspects we were discussing the perfect game, and we came up with the interesting fact that apparently it was a fluke that Johnson's perfect game and Jason Schmidt's one-hitter last night were both on the road. Only of 5 of the 15 perfect games since 1900 (including Johnson's) were on the road. Furthermore, I did a rough count based on this list of no-hitters and came up with almost exactly the same proportions: only 77 of 225 no-hitters in the history of MLB were on the road.
