I think Oakland will be a prime trading partner.
After this season, the following Oakland players are due for raises in arbitration: Matt Chapman, Matt Olson, Ramon Laureano, Chris Bassitt, Frankie Montas, Sean Manaea, and Chad Pinder, and Lou Trivino and a few others.
No way they can keep them all, and probably a huge factor in why they acquired short term money in Starling Marte at the deadline.
I figure they could easily reach agreements with Bassitt and Pinder and will desperately try to work something out with Chapman. But they might be trading some/all of the rest for financial reasons.
Since Marte (and Mark Canha!) will obviously be moving on, and Laureano might as well, a Jarren Duran/Frankie Montas deal in some form might make sense for both teams. (They are unlikely to be as interested in Verdugo over Duran, since Verdugo is also arbitration-eligible.)
