This is not an original idea or anything, I know I’ve seen them around, in various permutations and combinations, and maybe in almost exactly this form, too. The data is all from ESPN Home Run Tracker. The length of the line is the related to the speed off the bat, and the elevation angle contributes the angle of the vector. I also differentiated HRT’s main classifications by color. “No doubters” are in red, “Plenties” are in blue, and “Just enoughs” are in green. (The colors didn’t exactly come out perfect). I believe the speed off the bat is just calculated from the distance and angle, but it’s there to give an idea of the pure amount of force.
The best comparison is Bailey (above) and Arroyo. Bailey’s let a lot of low, hard hit go over the wall in Great American, but Bronson’s home runs are coming on a lot of higher flies. You can see how hard hit Bronson’s no doubters are, too.
Then, of course, you have Johnny Cueto, who makes my life easy by not giving up home runs.
Mat Latos has also had a few high flies – but also has a bunch of low, just-enough home runs. You can see where he would have done much better in PetCo’s spacious confines.
Mike Leake’s had a little better overall luck with home runs than Latos, or Bailey, but he seems to have a smaller proportion of GABP-specials.
To be honest, I don’t have a lot of analysis on these – I just thought they were pretty. And maybe a little interesting.
