Cubs prospect Amaya called up as Gomes hits concussion IL.

The Chicago Cubs have several prospects making waves in the minor leagues, including catcher Miguel Amaya who has been called up to the majors for the first time. The Cubs are also closely monitoring the use of pre-tacked baseballs in the Double-A Southern League, where their affiliate team Tennessee Smokies play. Other notable prospects include Pablo Aliendo, Haydn McGeary, and Brandon Birdsell, who have all been performing well in the minors. The Cubs are also continuing to sign international free agents, with 17-year-old righty Nestor Pirela being the latest addition.
