Yes, you know more than the guy who covers the team. Everything the Phillies have done says Rojas is guaranteed a spot. I'll agree his poor numbers crack the window to option him but they've also made it clear spring training stats don't matter as long as he is working hard and having a decent process. If they do demote him Pache will get more starts total than Merrifield every week (certainly Merrifield would get a few more, especially since Cave isn't necessarily better than him against RHP).
Both Schwarber and Thomson have said he'll play LF, maybe 5% of the time. That's only eight games. Schwarber wants to play in the field at least a little, and Thomson wants to be able to put others at DH a bit without actually sitting the big slugger.
Cave should not be guaranteed a spot, but they won't necessarily find someone better, just different (Dahl, or someone who's on another team right now).
Castillo is a AAA starter, he's not on the MLB roster. Covey being injured makes it easy to keep him for now (and then he may well clear waivers if they don't bring him back onto the 26). And Ortiz has options. Both the 7th and 8th spots in the pen will be held by 10 different players in the next three months. It's far more important that the 5th and 6th guys (Soto and Kerkering) work out. And that Hoffman is what he was last year, and Seranthony isn't.
Gelb thinks Brogdon is done but if they see him as just a mop-up guy they might try to hang onto him a little longer. Of course he could also clear, he has not been good since the '22 World Series. But he was good.
