DD playing 18U, bases loaded when our speedster left slapper gets up. Def has seen her and move in to try and get the play at home. She laces one hard down the RF line and it rolls to the fence. Runs come pouring in and here she comes, stand up in the park Grand Slam. I would have been hard pressed to believe it had I not seen it. Fields were 220 to corners so that did help and the fact the D was playing short. The girl is just unusually fast.
