First is Nick Senzel. So much anticipation came with him whe he was drafted. Seems like many put everything on hold until he got to Cincy. He was going to be the savior. Injuries seem to have hampered him but staying healthy is part of the game. It's time for him to live up to the promise.
Second would be Tyler Mahle. He has shown flashes of being really good but lacks consistency. He should have the age and maturity to develop into a solid 3 or 4 starter.
Third would be Nick Lodolo. No play last year might not have helped him but he has tremendous talent and potential. He needs to show some brilliance in the minors this year and maybe a September call up. He is just 23 but he needs to position himself to start in the majors in 2022.
Last, but not least, is Hunter Greene. If there was ever a good time to have TJ surgery it was last year. This needs to be a year of getting in the innings and regaining confidence in his arm. He is still very young but if you are considered a generational talent you have to make a splash early.
