I have no idea how to read all that. Does the 1.5 spread mean that if someone bets on the Dodgers, and the Dodgers win by 1 run, that the bettor loses the bet?

Positive number = what you get if you bet $100 and the team you bet on wins

Negative number = what you need to bet to get $100 if they win.

So if you bet $100 on the Nats, and they win, you get $232 (your $100 + $132).

If you bet $152 on the Dodgers, and they win, you get $252

I believe the spread takes into account odds of winning/losing by a set number of runs (in this case 1.5).

Total = total # of runs

Bottom line, we're big underdogs.
