Yes I could cancel the bets and I have. Unfortunately the automatic limit to bet is half what I could bet for the world series. There is a note to contact support if you want to bet more, but I haven't had time yet. Apparently lots of money going on LA Angels to make the playoffs, May 22nd was +1500 and now +1100. All I can say is yes I've never bet sports before because it isn't smart unless you know something, so hopefully I'll stop.
