Hi Jack, I've seen your video on the angle of lead arm stays constant from toe-touch to contact. And that is true in MLB. But I've seen videos from Asia (Japan & Korea) that some asian players get their lead arm extended at the contact as they get older:

(144 km/hr:89.5 MPH fastball)
(Tomoaki Kanemoto from Hanshin Tigers in Japan: retired after 2012)

(141km/hr:87.6 MPH fastball)
(Lee Seung-yup from Samsung Lions in Korea)

(Both players are power hitters and hits HR from videos above)

What will be the difference in their swing compare to Major League players such as Ken Griffey Jr, Chipper Jones, Adrian Gonzalez, etc? what did they (asian players) have done right to achieve the HR?
