Jesus christ that is why i dont bet baseball. A year ago I actually fired a few k on a random game in Vegas because there was nothing else to bet on. I took action but they switched pitchers like 5 times before the game even started and the Cantor system got all fucked up. Instead of assigning the new odds based on the picture, it told me my ticket was a loss when I tried to cash it in. Luckily, I thought about it , went back to the sportsbook, and explained what happened. They then took my "losing" ticket out of the pile and did some calculation based on the odds before the game started and then paid me. Had I just walked away I would have been out 3-4k So you really need to know the rules your book has before placing baseball bets because even they can fuck it up.
btw, I still think they fucked me because i thought "action" applied no matter how many times they switched pitchers and you were locked in at those odds. But it ended up being the difference of 40 bucks, and I just didnt know enough about baseball betting to be confident i knew what i was talking about
