Note. I have added links to ballpark diagrams for all of the parks Carlton has pitched in so far to give you a better idea of what he was dealing with. Most of the cookie cutter multi sport stadiums he pitched in were larger than those of today. Also, half the stadiums in the National League in 1972 were covered with artificial turf (Cin, Hou, Phi, Pit, SF, St.L), with Cin, Phi, and SF having complete coverage (with only base cutouts) in 1972. The site I got this information from is pointed to in the introduction (dated in red) and is one of the most exhaustive, entertaining sites about baseball that I have seen. The Park diagrams and photos alone are worth a look.
Carlton, by the way, got bombed, but the Phillies came back to win one of the uglier games of the season. It was their 5th win in their last 31 games, and broke a 6 game losing streak
