I just read a thing on SNY that even though Vargas was only 74 pitches, Calloway's plan was Vargas for 5, then use 3 relievers for the next 4 innings (that was a quote from him). I'm not sure why that formula was etched in stone, especially since Calloway revealed that Seth Lugo was sick last night. Shaky as Vargas was, they could've (probably should've) tried to squeeze another inning out of him, especially with Familia and Diaz unavailable/Calloway'd.
