The Yahoo article could have been written by the umpire herself. She will continue to improve...... How long with that take and what sort of improvement have we already seen?
If she needs to improve, she needs to train in A Ball with the “Lansing Lugnuts” or similar.
I would not assume that.
Calling a strike and a balk on the same pitch would be highly unlikely even for a pee wee league umpire, and she's been playing and umpiring for decades in softball, women's baseball, and in the minor leagues. If she hasn't "leared" it by now, she likely never will.
