Personally, I don't really understand why vegas gives you 2 options when listing pitchers or do you just want action?
Here's my beef with this... when I was a young gambler... let me give you an example of a story...
Let's say Randy Johnson in his prime was coming back from an injury and you had inside information that he was going to start... but the line was already up for some other pitcher at -130. But you knew if Johnson got the start the line would be -180. You quickly select Arizona (Action) no matter who throws at -130. Which means... doesn't matter who's listed... you have action.
Then, game time comes... your info was right on... and Randy Johnson is starting. Vegas quickly removes the former starting pitcher... and now lists Randy Johnson... with a new line. -180. You're all excited because you though you had "ACTION" no matter what.
Come to find out... when you have "ACTION" vegas is still allowed to take your initial wager and adjust your risk amount accordingly with the "new opening line" and then if you win... pay you accordingly.
Maybe I'm one blind fuk who doesn't really understand any secondary reasons for this. But why in the fuk do we have ACTION and LISTED PITCHERS. When honestly... it doesn't give you an advantage what so ever? It is the stupidest rule ever. The way the rule is set up you'd be a dumb fuk to ever go ACTION on any MLB game. Listed Pitcher always protects you. But Action never protects you.
Dumbest wagering rule in vegas ever.
