Shane Greene isn't guaranteed a rotation spot entering the season after spending the final two months of 2015 on the DL, but he'll be one of the more fascinating pitchers to watch in spring training. He dominated out of the gate last year, allowing one earned run on 12 hits over 23 innings in his first three start but then did a sudden about-face and never really recovering. Little did anyone know, though, he had an artery problem in his right shoulder, which created aneurysm symptoms in his right hand. He had complained of numbness at various points during the season, so it's reasonable to think it may have contributed to his struggles. With the surgery behind him, Greene could come closer to the numbers he had as a rookie for the Yankees in 2014, but barring a sensational spring performance, he's a sleeper better left for AL-only leagues.
