If the Cubs believe that Olt is "fixed" and is a potential long term Major League player, is there any chance they send him back to AAA for a few months so he doesn't accumulate the service time? He would only need to stay down a few more weeks than Baez. With his age and the organizational depth at 3B, I don't expect they would send him to AAA if they believe he is ready, but I wouldn't put it past this front office to want to buy themselves another year. I believe they would be better off giving Villanueva all the reps at 3B in AAA and starting Olt in the majors. Gives us the chance to showcase another above average trade chip every day at his natural position. Which one is the trade chip in this scenario?
