Correct score:
Ghana 1-0 USA +550
Ghana 1-1 USA +425
Reasons:
1) It's unlikely that either team will score more than once
2) If any team will keep a clean sheet, the records suggest Ghana is the more likely to do so
3) While this looks like going into OT, I think it'll end within regulation time
4) By the law of randomness, I expect the dog to win the second game after the favorite (Uruguay) won the first game
