Bello, 22, pitched 24 1/3 innings for the Yankees' Rookie-level Gulf Coast League affiliate this season and posted a 6.29 ERA with 29 strikeouts (10.7 K/9) and 16 walks (5.9 BB/9). Bello will turn 23 this winter and has yet to pitch at a higher level than the GCL. In parts of four seasons between the GCL and the Dominican Summer League, the Dominican native has posted a 3.98 ERA with 10.1 K/9 and 4.5 BB/9.
That the Rockies didn't receive much of a prospect isn't a surprise, considering the trade occured after Nelson had already been designated for assignment. Nelson spent just two weeks with the Yankees, batting .222/.243/.278 with 11 strikeouts and one walk in 37 plate appearances. They would soon DFA him as well, and Nelson would go on to be claimed by the Angels.
