That Jason Kidd, the former NBA player who was fired from coaching the Milwaukee Bucks in January, is in contract to sell his apartment at the Aldyn, located at 60 Riverside Blvd. on the Upper West Side.

It was last asking $5.35 million — down from $5.99 million in late 2017. (Kidd bought the unit for $4.27 million in 2012.)

The four-bedroom home measures 2,755 square feet and features Hudson River views. There’s a windowed eat-in kitchen, a corner great room with floor-to-ceiling windows, and a master bedroom with three walk-in closets.

Building amenities include 40,000 square feet of “play space” with a gym, a pool, a Pilates room, a dance studio, a double-lane bowling alley, a basketball court, a squash court, a steam room, a sauna and a courtyard with hammocks.

The listing broker is Douglas Elliman’s Andrew Azoulay, while we hear that Elliman’s Alexander Boriskin and Michael Lorber repped the buyer.
