Skaggs was #13 last year on baseball america's listings. Randall Delgado was #46 two years ago. So, if they are willing to move both those I think a deal is there to be made. Those two plus one or two of Braden Shipley, Zeke Spruill, Jake Barrett, Anthony Meo and Andrew Chafin for Shark and Schierholtz whom they've reportedly had interest in would make sense. It would also leave AZ with a lot to play with in their minors in terms of arms in their system as they would still have numerous young guys at the MLB level as well as several guys from the list above and Bradley.
Another thing I had thought about was the Yankees if they could find a third team like the Marlins who had young pitching. Shark at $5 mil is something that would entice the Yankees as they currently sit about $30 mil from the luxury tax and need 2 starters and possibly still want Cano. They have 4 top 100 prospects but only 1 is a pitcher and he's in the 90's. If the yanks gave up some grouping of Gary Sanchez, Mason Williams, Tyler Austin or Rafael De Paula and parts and got Shark with Miami giving up Andrew Heaney and other parts to the cubs with the Marlin's getting the yank's offensive guys I could see that happening. That being said, if AZ would give up Skaggs and Delgato I personally would prefer that package.
