Bellinger, Verdugo and Calhoun are ranked as the No. 1, No. 3 and No. 4 prospects in the organization, respectively, by MLBPipeline.com.
Bellinger, 21, was just promoted to Triple-A after hitting .263 with 23 homers and 65 RBIs at Double-A Tulsa. The son of former Yankees utility man Clay Bellinger, Cody signed for $700,000 as a fourth-round pick in 2013. Bellinger is a left-handed true first baseman, but he is athletic enough to play the outfield comfortably.
Verdugo, 20, signed for $914,600 as a second-round pick in 2014. A left-handed-hitting outfielder who had a 94-mph fastball as a two-way player in high school, he hit .275 with 13 homers and 62 RBIs at Tulsa.
Calhoun, 21, is only 5-foot-8, but he is showing Joe Morgan-like power as a left-handed-hitting second baseman taken in the fourth round last year. He hit .275 with 27 homers and 88 RBIs at Tulsa this year. A lack of true middle-infield defensive skills could send him to the outfield.
