    O's board has already started to crunch, and is threatening to
    deteriorate further since O will be cautious about breaking
    anchor in the face of X's outfield coverage and five-point board.
    This looked like a clear double to me, but XG disagrees. The race
    is basically even and if O hits a shot then it will immediately
    turn the game around.
