- I am not a big fan of starting out with the glove over the head, just seems to be wasted movement, but many claim it is only stylistic (i,e, Cat Ostermann) and has no impact on pitching mechanics. I'm not 100% convinced of that.
As someone who uses it, it is purely stylestic. It gets me into the rhythm much better than a smaller pump does. No extra effort is required on the pitcher's part at all.
