My guess is there would be just based off being able to push off, but this group has so much more experience I figured there might be some anecdotal dataI was curious about the original question before rubber was changed to rubber. Always wondered if there was a speed difference from just pitching off a spot in the backyard vs off the rubber.
Agreed of course. And those things are given. I’m actually just curious about the specific point of whether a pitcher using a rubber would have more speed than withoutVelocity is only one part of a pitching workout. Also, a pitcher needs to get used to warming up without a rubber. The vast majority of fields that are used don't have a bullpen, or a bullpen with a rubber, for the pitcher to warm up on. At most travel ball and varsity fields that I have seen the pitchers warmup in the area between the baselines and the dugouts. For an accomplished pitcher not having a rubber may make a difference.
