Julius Randle capped his All-Star season with 20 points, seven rebounds and seven assists, and the Knicks beat the Boston Celtics 96-92 on Sunday to clinch the No. 4 seed in the Eastern Conference. The Knicks are headed to the postseason for the first time since winning the Atlantic Division title in 2012-13.

“We’re fighting for something every single game and that’s a good feeling,” Barrett said.

The Knicks entered the day tied with the Southeast Division champion Hawks, who played later Sunday against Houston, but own the tiebreaker if they finish with the same record after sweeping the three-game season series.

The Knicks were one of the NBA’s biggest surprises in Thibodeau’s first season after having little to no playoff expectations outside the organization.
