This is interesting (I always used Listed because I had the mindset that "I am paying/getting price based on the assumed pitching matchup").
I always thought that --with an Action bet-- the PURPOSE of allowing an action bet is to just select THE TEAM, rather than the pitcher himself.
So by allowing me to have an Action bet for an away, underdog team playing their 5th pitcher at +180.... it's for the TEAM, not the PITCHER.
Now, if the other team's ace pitcher gets scratched & the other team now plays the 3rd pitcher and the lines are adjusted to +130/-140.... my "Action" bet would now be +130, not +180 even though I picked the same team hours ago? Essentially, the book is now renegading on their honor on an ACTION bet by changing the lines after both me & the book have consented to a valid wager??
Personally, that's ridiculous.
