The Philadelphia 76ers protected their home court and extended their winning streak by beating the New York Knicks 99-96 at Wells Fargo Center on Tuesday.The Sixers' six-game winning streak is their longest of the season, and it came at a time when star center Joel Embiid is on the injured list.Ben Simmons and company were trailing most of the game, but a late surge highlighted by key defensive play gave them the momentum they needed to arrest the lead from the visitors. Simmons almost had a triple-double with 16 points, 13 rebounds and seven assists.Tobias Harris led all scorers with 30 points and six rebounds, while Seth Curry had 20 points on 7-of-12 shooting from the field. The two combined for 8-of-13 shooting from three-point territory which was crucial to the Philadelphia 76ers taking the lead for good.The New York Knicks came out sharp earlyA few Knicks fans made the trip to Pennsylvania, and the Philadelphia Sixers broadcasters thought it was unusual during this pandemic.Tobias Harris' team found themselves in a hole at halftime with the score at 56-48. After trading baskets for much of the first half, the New York Knicks were able to put on the afterburners in the final four minutes.Julius Randle, in particular, continued to showcase All-Star form in the first half as the Knicks seized control of the second quarter with a quick burst.Knicks up 56-48 at the half.@J30_RANDLE with 13 PTS, 7 REB, 4 AST already pic.twitter.com/58hvp6OfJB— KNICKS ON MSG (@KnicksMSGN) March 17, 2021RJ BARRETT WITH AUTHORITY pic.twitter.com/Rf3CNG2KVn— NEW YORK KNICKS (@nyknicks) March 17, 2021Some Knicks fans in the house chanting MVP w/ Randle at the line. 76ers drowned 'em out with artificial noise.— Dan Gelston (@APgelston) March 17, 2021I loved Randle as a Lakers fan. It's great to see him put it all together. He has such an amazing motor and has always been a beast.— Seth (@seth_3333) March 17, 2021Knicks not a easy win anymore, especially tonight coming off of a controversial loss #HereTheyCome— Kevin Shell (@shellone2010) March 17, 2021Julius Randle #30 against Jarred Vanderbilt #8 of the Minnesota Timberwolves.

Mixing up his attack with threes and drives to the basket, the veteran guard practically carried the Sixers offensively.Stopping the New York Knicks was another matter altogether, though.Make that a 4-point play.📺 @NBCSPhilly | @sdotcurry pic.twitter.com/DwtohmCZco— Philadelphia 76ers (@sixers) March 17, 2021Seth Curry with a couple of deep 3s here to start the 3rd quarter. Side-stepped into a 3pta earlier in the game as well. Sixers still struggling to stop the Knicks, but it's nice to see Curry let them fly like that. Would help the Sixers if he can get his 3pt volume up a tad.— Derek Bodner (@DerekBodnerNBA) March 17, 2021This Seth Curry run is too much for me 😐— Teron N.
