I don't like that your BP loses energy. I've played a total of 2 Event games, that went to extra innings and now my WHOLE BP is in the red.
So I can either forfeit my 2-0 run and select new arms or hope that my relievers can play with low energy.
On a side note; how long does it take for a player to replenish all his energy?
And why does it seem like that once you throw 1-2 pitches (SP or RP) their energy automatically drop a to the next color?
