Here's a few trades:
Brewers: Lowe (12.8 BTV)
Rays: Mitchell (10.8 BTV) and Blalock (1.9 BTV)
Rays get a controllable and cheap often injured but talented player. Brewers get a less controllable and often injured, more expensive player that fits a need now and in 2025. Arnold has mentioned the team wants a left handed bat and Lowe fits that need.
Brewers: Kikuci (5.2 BTV)
Jays: Wichrowski (4.2 BTV) and O'Rae (Probably around 1.0 BTV)
Kikuci would strengthen the rotation for the stretch run. The team likely would prefer to add a lefty to their right handed dominant staff. The Jays get a promising young starter and a speedy Canadian prospect.
Brewers: Fedde (21.4 BTV)
Sox: Black (13.3 BTV) and Wiemer (7 BTV)
The Sox needs an influx of talent at many positions. Black doesn't really have a defined defense position and can learn where that is on the job. Wiemer has been hot lately and provides a boom/bust player with plus defense. Fedde provides a playoff caliber starter that can be plugged into the rotation in 2025 as well.
I also think they will trade either Milner or Payamps but I could not think of any good destinations or values there.
