I'm happy the guy won, but I'd like to show why its important to check the max parlay payouts. In this case it was $150,000. (unfortunately he loses out on over 67K). His parlay paid $217,094. 23. So it made no sense for him to take the extra risk in the parlay, he could of made it closer to the $150K max payout:

Instead of taking Seattle on the moneyline, he could of took them on the runline +1.5 runs, and still been over the $150K max payout. Imagine if Seattle would of lost by 1 run, and his parlay would of lost.
