Julius Randle says the New York Knicks won't get carried away after extending their winning streak to four games on Saturday, when his 39-point haul helped them past the Washington Wizards.

Randle finished two points shy of his best return of the season as the Knicks improved to 21-15 for the campaign with a dominant performance at Capital One Arena, earning a 121-105 win.

The Knicks never looked back after bringing up a 26-point lead in the first half, building on their impressive 128-92 victory over the Philadelphia 76ers one day earlier.

They are now up to fourth in the Eastern Conference standings, but Randle says they are not looking too far ahead and will continue to take things game by game. 

"Don't play with your food," Randle said after Saturday's win. "Take care of what you're supposed to take care of and just keep improving. 

"The basketball gods have got a funny way of rewarding you or humbling you. We just try to approach every game the right way."

Jalen Brunson supported Randle with 33 points and eight assists, and the 27-year-old is enjoying playing with the two-time All-Star.

"Collectively, we both have the same mindset," Brunson said of his team-mate. "As long as we're winning, we can get better the next day and keep going from there.

"It was important to come out with energy, especially on a back-to-back. It's fun whenever you're winning."
