It turns out, Miguel Sano is considered the top prospect and the Yankees are said to be very interested in his proceedings. Right now, the reports have the Pirates in the lead, but the yankees have been working him out over these last few weekss, we'll see.
As it turns out, the yankees are expected to sign catcher Gary Sanchez. He's a consensus top 5 free agent coming out of this group and also considered to be the best power hitter of the bunch.
Wagner Mateo is another big ticket OFer who is also considered a top 5 prospect. He has been linked with the yankees since his name came on the radar and some scouting services think he'll end up signing with NY for $2.5-3 million
Another outfielder by the last name of Pimental was linked with the yankees. But recently, NY placed a grievance with Texas on Pimental's behalf. It is now believed that the Rangers will be signing Pimental, although the grievance is still pending. Apparently, the Rangers held onto Pimental for more than 2 months in their facility which is a rules violation.
The pitching market got weaker as a righty by the last name of De Paula was suspended. He was a guy the yankees and sox were battling for. Throws mid 90s with a good changeup, but it turns out he altered his birth certificate. MLB instituted a new rule requiring a 1 yr suspension on signing for players who alter their BC. Turns out, De Paula is 18. He'll still be a hot commodity next yr, though.
