Kremer is Arb 3 eligible for '27, same as Ober, they will get about the same $$$ next season.
Kremer has the most fWAR as a pitcher on this team since August 1. Ober has the second most. Tough decisions must be made as a lot of SP that were part of the team's future plans will be coming back from injuries next season. Both may be back, neither may be back.
Royce has 2 Arb years left, he has about 3 weeks worth of games left to see if he should be a part of those 2 years. He won't bring back much in a trade, but as part of the right package, another team may take a chance on him.
Larnach is replaceable yesterday. He has no trade value, but some team will offer a low A player for him.
