It's not a perfect comparison, but this feels like the Varland situation from last year, a little to me. With the main difference being the length of success Sands has had in the Major League Bullpen (1+ years) compared to Varland being more like half a season by the start of 2024.
The Twins, it seems, wanted to just make sure that Varland as a starter was no longer viable at the beginning of 2024, giving him a rotation spot to start the year and then keeping him stretched out when he went back to AAA, before finally realizing (I think) that Varland is better suited as a reliever.
Like I said, the situations are a little different, but I could see the 2025 Twins wanting to just make sure that Cole Sands as a starter is no longer viable.
