golf 3-ball betting - odds on a half win, half push?

[MalikHusam]

Need some help, could someone explain the math to me?

Smith/Burns/Thomas today, I had +150 on Justin Thomas in a 3-ball

-4 Thomas
-4 Smith
E Burns

So what are the odds I'm paid at?

Originally I had $100 to win $150, but now $100 to win... ?

I think you'll get back $125 ($25 profit). Two players tied for the top spot so half of your bet wins and half loses. Your $100 to win $150 is reduced to a winning bet of $50 to win $75. That's my take. Hopefully someone else can confirm or correct if I'm mistaken.

BTW, how did your Book grade this?
