Mets slugger David Wright is putting his Flatiron penthouse back on the market for $6.25 million. That’s far less than its peak asking price of $7.85 million last year, reports The Post’s Jennifer Gould Keil. The 4,100-square-foot, four-bedroom bachelor pad includes a saltwater aquarium, gas fireplace and a media room with five flat-screen TVs, as well as a chef’s kitchen and 4 1/2 bathrooms. A private roof deck includes a hot tub, sound system and gas grill. Wright’s rarely been spotted at the address since moving to the Upper East Side’s Lucida building, as The Post previously reported. Listing brokers Juliette Janssens and Allison Koffman of Sotheby’s declined to comment.
