Here are my keys, in order of importance:
2 of the 3 young LHSP's, Hall, Gasser and Ashby, must be solid to good. My definition of solid is 20+ starts and 110+ IP @ sub 4.2 ERA. I have the players ranked in the order of probability of being solid. I honestly believe Hall could be good this year. Gasser will hover around the solid mark. Ashby is the absolute wild card, with this injury and command issues.
Health for the middle of the order. Hoskins, Contreras, Yelich, Adames need to get 500+ PA's. You don't have to squint very hard to see a playoff caliber heart of the order between those 4 players. No one can predict health but if they hit the 500 PA threshold, this will be an above average offense, which is an improvement from 2023.
2 of the young guys have to grasp roles. Chourio, Frelick, Ortiz, Mitchell, Turang, Black, Dunn etc are the group I am currently interested in. Once again, I have them ranked in confidence level order. With the volume of talented players in this group, it would not be surprised if at least 3 are 2 WAR players.
Colin Rea!!!! This guy gets the least amount of press and analysis because he is boring, but I think he was our 3rd best starter last year. I value IP more than others, so if you disagree I understand. Based on what I have seen, he has improved his heater and added another secondary pitch. He doesn't seem to be nibbling as much and just trusting his stuff. Possible 3+ WAR season in 2024.
