There is so much more research needed to fully understand everything there is about weighted baseballs. So far, here is some of what we do know in a quick summary: Throwing Velocity Using an array of weighted baseballs (4-12oz.) can lead to an increase in throwing velocity. One study [1] found that using over-weighted baseballs as a warm up greatly improved both throwing velocity and accuracy. These results are great, but they lack ecological validity (carry-over effect). Will a pitcher ever warm-up with a non-regulation ball between innings? Probably not.
