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. He's got 63 days of service time already. You'd have to hold him down half the year. My calculations were apparently a bit off.
