It's more likely Robert would go from AA to MLB than A to AAA. Better talent is in AA than AAA. I would rather he gets a good bulk of time in AA. AAA rosters have a bunch of depth type of guys for when the MLB team has injuries.
I think they hope he has another 2-3 WAR season in hope of dealing him to a contender in need of a 2B (or just IF depth in general) in June/July.
But besides that, most, if not everyone, here want Rondon in the lineup.
