Wall made four free throws in the final 6.6 seconds and the Wizards held on when Langston Galloway‘s 3-pointer at the buzzer was just short.
Carmelo Anthony had 33 points and 13 rebounds, but the Knicks lost their sixth straight in their first game since firing Derek Fisher on Monday. They have dropped 10 of 11 and started Rambis’ era the same way Fisher’s ended, by quickly falling in a huge early hole.
Rookie Kristaps Porzingis scored 20 points, but just two after his 14-point third quarter.
Beal also took a charge against Arron Afflalo when a video replay overturned what had been ruled a blocking foul on a basket with 44 seconds left, a play that could have cut Washington’s lead to two.
Wall then kept the Wizards ahead with his free throws and they won for the third time in nine games. The All-Star made the go-ahead basket midway through the fourth, and later added a pair of jumpers before a 3-pointer that seemed to put it away at 106-96 with about 1:50 left.
The Knicks fired Fisher on Monday and appointed Rambis the interim coach through the remainder of the season. Drafted by the Knicks in the third round in 1980, Rambis said for the second straight day that it’s important for the Knicks to get into the playoffs, but that will take a huge turnaround after the All-Star break.
They allowed 63 first-half points, trying their most this season, after he said they had to toughen up their defense.
Porzingis hit a couple of 3-pointers early in the third, but his signature play came much closer to the basket, when he spun baseline around Jared Dudley and threw down a powerful dunk with Marcin Gortat nearby. That put a buzz in the building as only the rookie can and it stayed there as the Knicks caught up at 83-all to end the period.
But Porzingis was on the bench to start the fourth and the Wizards had just gone ahead for good before he returned.
