What the ladies are doing is guessing wrong. They expect the rise, they get the change. They expect the change, they get the drop. They expect the drop, they get the rise.....etc. They're swinging like this because they are fooled by the pitch. You can throw mechanics out of the window when you guess.
Those were my thoughts. This is a great pitcher, and it's a video of HER highlights, not the hitters'. Maybe these hitters need work. But it reminds me of the line used by Mike Tyson - "Everybody has a plan until they get punched in the mouth.'' It's hard to look good when somebody who's better than you just knocked you on your rear.
Those are two pretty good posts!
