NEW YORK -- Derek Jeter's swinging 88th-floor New York City penthouse has just gone back on the market for a discounted $17.95 million, down from the $20 million price of two years ago.

The 5,425-square-foot captain's quarters is atop Trump World Tower at UN Plaza on the East Side.

It boasts 360-degree views of Manhattan, four bedrooms, five and a half baths, an eat-in kitchen and a fireplace.

The ladies' man's lair has ultra-suede wallpaper covering the 16-foot-high walls. There's a pool table, a poker table that seats eight, a dining-room table with room for 14, and even an old-school bar tabletop Pac-Man game.

The Yankees shortstop is apparently looking for something smaller after splitting with gal pal Minka Kelly.

"He is downsizing to a Manhattan pied-a-terre apartment," his broker, Carrie Chiang, of the Corcoran Group, told The Post.
