When it's said they are controlled through 2025 it means right after the 2024 season ends is considered 2025 seasons. So if say controllered till 2022 would be after this current season starts and ends with world series the off season be considered 2022. Corbin would be 2025 so he's a free agent as soon as the 2024 season ends. Would be 4 yrs of control if you got him now
