Point still stands. I get that they want to get a look at Rios, but he has an option. I still don't get Torrens...guess they put him in there vs. lefties but Vazquez hits better vs. lefties, and Torrens has only caught 3 innings this year so its not like they desperately need another option at catcher, they need a DH vs. lefties.
So its likely the same reason they have Morel down at Iowa, they want him getting consistent ABs. I'd throw Mervis in there too but the excuse doesn't fly when your current 1B options are barely hitting better than pitchers did.
