With the normal caveat that teams value players very differently internally, and don't make trades by pulling out the MLB Pipeline rankings and saying, "I'll take a four, a seven, and a 12," the New York Mets just objectively threw a wrench into the rental reliever market before the Yankees had a chance to make their first play in an area of need. That's what you get for waiting closer 'til the deadline and making three lineup changes before a pitching move.
Austin Slater and Amed Rosario represent real depth upgrades. Ryan McMahon didn't feel flashy at first, but the ease with which he fielded two dribblers in the ninth inning last night might've directly won the Yankees a second game during his short tenure.
