Breslow spent a relatively small amount to get "help" for the rest of 2024's season (56 games) . Nick Yorke never made the 26 man so you can't miss him, and neither did any of the other guys traded who were probably Rule 5 problems over the winter.
But you have to balance that with the fact that Sims, Ramirez, Paxton, D. Jansen, Garcia are all free agents after September 29 , along with Kenley, Martin (IL) and Pivetta, So roughly half of the current 13 pitching spots on the 26 man need filling over the off season.
Breslow still has a lot of work to do going forward. The trade deadline was pretty much smoke and mirrors.
