I think your logic goes against your conclusion. Jimenez physical abilities got him through the minors but when he hit the MLB, he needed to learn adjustments and the league. These are things he couldn't learn in the minors. He needs to adjust at the MLB level. The same will apply to Robert. Extra time in the minors will not teach the adjustments needed at the MLB level. The competition is just better. He needs to move up a level once he adjusts and learns at that level.
