Putting myself in their shoes, they absolutely need to either extend him or trade him. They'd be extending him at peak value, probably looking at Buster Posey money or close to it. Posey was extended at age 25 after his MVP season and got 8/160 with 3 years of arbitration bought out. You figure a Realmuto deal is probably close to $20m per right now over 5 or 6 years...with 2 years of arbitration bought out. If the Marlins want to and are able to do that, good for them. Otherwise, trading him now makes sense. I generally disagree with this idea that so many more teams will be interested in the offseason. Teams generally don't get desperate in the offseason with no pressure to continue a postseason run. And rebuilding teams aren't interested in Realmuto now and won't be in November. No one thinks they're rebuilding in November. Okay maybe 5 teams or so do but the other 25 are going into the following season with the mindset that they at least have a chance as opposed to it being whittled down to 12-15 teams in July that still consider themselves contenders. As recently as 3 years ago I would have completely agreed, but doing a Cubs/Astros style tanking has become a thing lately. The O's, Blue Jays, Tigers, White Sox, Royals, Rangers, Mets, Marlins, Padres, and maybe the Reds are not in a position to win all that soon. Sure the overall market may be bigger, but there are free agents that can be targeted...and generally there is no desperation in the offseason. Right now, there's an outside chance they get a desperation overpay from the Nats. Whatever they offer will probably be better than anything anyone else offers in November. It really depends on what the offer is, but if the Nats get to a point where Robles is included...even if they don't offer much for good secondary pieces...they probably should do it. Same with the Brewers and Hiura or a Peralta + Burnes led package.
