2016 was certainly a year to forget for Luis Severino. The hard-throwing right-hander went 3-8 with a 5.83 ERA, struggled to gain command of his slider, and his fastball was getting crushed all over the yard. Severino failed to meet expectations last year after breaking into the majors in 2015, where he went 5-3 with a 2.89 ERA. 2016 was supposed to be the year Severino took a major step forward as a big leaguer, but it obviously didn't happen. Heading into this year, Severino's role in the Yankees organization was uncertain. Was he going to start games or come out of the bullpen? Was he going to begin the year in Triple-A? The only thing that was known for sure was that 2017 could make or break his career. The 23-year-old earned a spot in the big league starting rotation out of Spring Training, and it doesn't look like he'll give it up anytime soon. Severino blamed poor mechanics and inconsistent release points for his 2016 woes, but an old Yankee rival helped him get back on track.
