Since it's subscription material, I'll only cut out two short clips: Pros: Mateo is what scouts like to call a toolshed: some have projected him to own five plus tools. He put on quite the show in batting practice, as you can see in the video. One swing sent a ball over the wall in center field, an easy 400-foot shot. Mateo's game isn't just power, as he utilizes his plus speed on the basepaths and in the field. His arm has also shown improvement, grading as a 60 on the 20-80 scale with the display he put on for scouts at the event. Projected Team: He has long been tied to the Dodgers and Giants, with the Cardinals also mentioned. It has been confirmed that he is not locked into a verbal deal. The Giants brought a large contingent of their scouting brass to the showcase, and they're mentioned by many insiders as the leaders for Mateo's services. They're also my pick.
