This seems wildly overstated as far as the role of CLOSER, but no doubt, as the options dwindle, it seems certain they are going to cast their lot with Kerkering as a key piece. But Hoffman is also there. And Soto has literally been a closer. I think the bigger issue is still that they need the 7th (currently Bellati or Brogdon) and 8th (currently Covey) guys to be optionable
Or, as the story says, they are still shopping:
The Phillies were in touch with righty Phil Maton, according to multiple sources, but nothing has materialized. They’ve expressed interest in Jakob Junis, a source said, though the 31-year-old righty would fit more as a multi-inning swingman than a late-game option. It’s likely the Phillies have engaged most other free agents, including Ryne Stanek, Adam Ottavino, Ryan Brasier, and Neris.
