If the Sox are serious about winning, once Mona's bat goes away, they should call up Arias. Have him hit 9th. Tell him to just put the ball in play and provide good defense. He's better than Cheng and is the long term replacement at SS. Why wait if you truly believe all players at AAA are ready to be called up? He's not seen as a franchise savior. He doesn't have that burden. It'd be showing up at the right time TBH.
