The Pittsburgh Pirates have promoted 2015 first round compensation pick Ke'Bryan Hayes to Morgantown from the GCL. Hayes put up excellent numbers in the GCL after being drafted, with a .333/.434/.375 line in 144 at-bats. He was praised at the time of the draft as a guy who could hit for average, get on base, hit for some gap power, and play strong defense. He did all of that in his pro debut.
The most impressive thing from Hayes was his defense, and that's considering the impressive offensive performance he had. Hayes is a smooth fielder with a good arm that leaves no question about his abilities to stick at third base in the long-term.
