Yankee hurler CC Sabathia was thrown an elaborate 37th birthday party by his wife, Amber, on Monday — a day off for the team.
A country club pool in Tenafly, NJ, was turned into a Vegas-style brunch bash that raged till after 10 p.m.
Shortstop Didi Gregorius was seen sliding into the Knickerbocker Country Club pool on a giant inflatable slide set up for the occasion.
“The weather wasn’t that hot, but Didi was in his bathing suit up on the slide with a bunch of guys from the clubhouse,” said a spy.
Luxe cabanas were installed, with cigars, lobster rolls, pizza and other goodies.
