change would do him well, but what does his fb do? one of my guys, at 14u was undersized and soft throwing. i taught him a sinker and had him play catch with it every day until the release felt natural. in games, he would use it as his main pitch and start it middle in and run it to the inside corner. when he got ahead, he could come back with his curve or a 4 seam above the hands. you wouldn't believe how many late swing and miss strike threes he got on his sub 70mph fastball. they were looking for soft stuff down and in so a 4 seam up looked like 90
any 4 seam below the hands got absolutely murdered, though, lol. there are some balls that still haven't landed, i think.
