Why do you guys believe that Appleby is a Hitter and not a Swinger who Paddlewheels? It looks like he uses 10-5-A and has the body rotation of a Swinger.
10-5-A is recommended for hitting as found in 12-1-0. He's using 10-10-C (angled hinging), which is also recommended for hitting but does not solely differentiate whether or not he's hitting. As far as 10-19-A (drive loading/hitting) versus 10-19-C (drag loading/swinging), you'd have to ask him. He's using 10-3-A (punch) instead of 10-3-B (pitch). His assembly point is 10-21-A (top) instead of 10-21-C (end). And he's using 10-22-B (random sweep) instead of 10-22-C (snap). His power package delivery path is 10-23-A (straight line) instead of 10-23-C (top arc and straight line).
If he's not hitting, he certainly missed a good opportunity.
