Would be curious to see what the average pitch velocity is now compared to 30 years ago? I remember back in the Jays WS days, 95 mph was considered serious gas, now there are so many pitchers that can throw 100 mph+ and bullpen are so much better! It makes sense that HR are up and averages are down. Ball is gonna travel further off a 100 mph pitch then a 90 mph pitch, but 100 mph pitch is gonna miss alot more bats. I wouldn't be surprised if offense continues to trend downward that we don't see some type of modification to the pitching mound, like they did in 1969 when they lowered the mound 5 inches. Mind you offensive numbers were much lower in 1968 then they are today though batting averages are about the same now as they were in 1968.
