Not exactly. When you DFA a player, there are 3 (or 4?) options that you must do within 10 days Trade him (at this time of year, requires putting him on revocable MLB waivers) Outright him to the minors (requires putting him on irrevocable outright assignment waivers). If he clears those waivers (which he won't), he'd have to accept the assignment. You have to have super-two arbitration status, three years of service time, or a previous outright in order to refuse and become a free agent. Release him, which would require putting him on release waivers, and he *would* have the option of refusing a claim and becoming an FA. I've seen some people say that if his roster spot is still open at the end of the 10 days, they can reinstate him, but I'm not sure if that's true or not. For practical purposes, that probably means he's being traded via MLB waivers. Or maybe there's something super wrong with him or maybe there's some kind of gentleman's agreement going on that will him clear to be outrighted. But he won't be a free agent unless they straight-up release him.
