TORONTO — With Monday’s 2-1 loss to the Toronto Blue Jays, the New York Mets have lost at least 50 of their first 85 games for just the second time this century. Since 2000, only the 2018 Mets have fallen this far this fast, making it clear more than a month ahead of the trade deadline the Mets will be sellers.What do they have to sell?This week, we’ll look at the Mets’ various trade assets and their potential returns. There are the obvious pieces to move in their walk years and the potential bigger moves with longer-term ramifications. Today, we’ll start with the rotation, where the Mets have already traded away 2025 All-Star David Peterson.Freddy PeraltaWhen the Mets traded for Peralta from the Milwaukee Brewers in January, it looked like the start of a long relationship. The right-hander was unabashedly excited to be in New York, and the Mets had dealt a pair of top-100 prospects, Brandon Sproat and Jett Williams, to bring him here.Instead, extension conversations went nowhere in the spring, and the Mets’ season is going nowhere in the summer — which means Peralta might go somewhere else by Aug. 3.Contract statusPeralta will be owed about $2.4 million after Aug. 3 and then hit free agency this winter. If he is traded, he cannot receive a qualifying offer this winter.Why the union should reject MLB's latest offerKeith Law2026 performancePeralta was acquired to be an ace, but his limitations have been more evident this season than his attributes. His first year in New York went from underwhelming to explicitly disappointing in that brutal start against the Philadelphia Phillies 10 days ago —what may go down as the last pivot point of a lost season. His ERA had been straddling 4.00 before that, with decent peripherals. (The strikeout rate is at a career low, however.) He enters Wednesday’s start against Toronto with a 4.53 ERA (4.16 FIP) and 91 1/3 innings over 17 starts. Just four of those 17 outings have met the standard of a quality start.The marketFirst, Peralta’s value on the market will depend on which other starters — Tarik Skubal — are available. (Joe Ryan, Reid Detmers and Sandy Alcantara were other starters ranked ahead of Peralta on The Athletic’s first trade deadline big board.) If the cost for Skubal is justifiably high and those other starters, all with control beyond this season, stay put, then Peralta should generate a lot of interest around the league.Several of the contenders most in need of pitching — think of the St. Louis Cardinals, Chicago White Sox, Athletics and Washington Nationals — might not be ready to trade prospects for a rental starter such as Peralta. Teams more invested in this specific season, such as the Chicago Cubs or even a Baltimore Orioles team talking about buying, could be more aggressive.
