We have previously discussed the 6 tool. Can pro scouts, college coaches scout this tool. It determines the win or loss of a game. It cannot be measured with the computer. Maybe in a discussion and definitely over a series of games.
Mickey Callaway, Cleveland Indians Pitching Coach exhibited this tool during our Goodwill Series in Korea against the National teams of Korea and Japan.
Javier Baez is an example. http://m.mlb.com/cutfour/2017/...after-a-weird-bounce
