If I bet a 3 team 5 inning baseball parlay and 2 teams won with the third team tied... do I win anything or do you lose on a tie?

Depends on the book.

I believe each SportsBook can have their own rules. I entered your question into to Google, and found a ton solid information. But, there seemed to be a common answer to your question. Give that a try. Then for sure ask your friendly staff member at the betting window for an exact answer... 💰💵💰💵
