Although he needs to still refine and harness his stuff Sanchez has better tools than Parker. Sanchez has the plus-plus FB and out true plus out-pitch to be a true ace. I like Parker, who also has good velocity but, he doesn't have the same upside as Sanchez. Don't get me wrong he does have a good shot to be a solid #2, he just doesn't have ace upside IMO. If the Jays are to be successful they need to develop their own star players. Selling off your top prospects for assets with a huge price-tag is an unsustainable strategy. Other organizations have sunk a large amount of money in to these players and have them under control for cheap for many years, they are in no urgency to move them. I'm sure AA could land a guy like Parker but, it will be at the cost of multiple high upside pieces against a GM with a penchant for pilfering talent.
