That is some horrible technique! She obviously has some "talent" as she gives it a good crack when it's in her strike zone, but as soon as she has to move a little it's game over for that swing!
I feel sorry for her as it's entirely not her fault, but poor, poor coaching. Imagine how good she could be with improved technique!
Don't be upset by the results you didn't get from the work you didn't do...
