With all the statistics available, is there a way of determining batting average by inning? I've been listening to all the dialogue about relievers and reading tales of glorious hitters of the past. I was wondering if the .350 hitters of the 40s and 50s got better as the game wore on or did the starting pitcher start wearing down in the later innings. Do modern relievers do a better job at handling batters than old starting pitchers did?
