It's the kind of thing where, if someone was holding that ticket - same with those St. Louis tickets from last year - you would have to ask how often they try plays like that. If it is a unique or rare play for them - and voila it comes through - then you just have to congratulate them. Jackpot. But if someone is making a regular thing of betting on miracles such as this year's Orioles going all the way, they are going to have a helluva lot of losing tickets that they aren't so anxious to show off.
A hell of a lot.
There are hedging strategies of course. You would get paid more often but less $$$. But still mostly straight-up losers.
I have heard claims of +ev long-term strategies for futures betting. But then I have heard claims of lots of things. Who knows?
Futures was never my thing at all.
