The New York Knicks blew an 18-point lead in a win over the Cleveland Cavaliers

The New York Knicks scored 18 unanswered points en route to a 109-93 victory over the Cleveland Cavaliers as they took a 2-0 lead in their best-of-seven Eastern Conference finals.

The score was tied at 53-53 as the Knicks took a 71-53 lead at their Madison Square Garden home en route to their ninth straight victory.

Josh Hart scored 26 points, including five three-pointers, for the home team as he tied a career-high for a playoff game, while teammate Jalen Brunson added 19 points and 14 assists.

The Knicks, who last reached the NBA Finals in 1999 and haven’t won a championship since 1973, had 19 points from Mikal Bridges and 18 from Karl-Anthony Towns.

“We don’t really care who gets the shine, the shots, the minutes, things like that — we’re focused on winning,” Hart said.

“I think everyone is willing to sacrifice their own personal agenda or performance for the betterment of the team. And when you have a team that does that, the sky’s the limit.”

Donovan Mitchell scored 26 points for the Cavaliers and James Harden scored 18 for the visiting team, who beat the Detroit Pistons 2-0 in the final round for a 4-3 series win.

“It’s not the first time we’ve faced adversity,” Mitchell said. “We’ve played two game sevens, so going 2-0 down is not the biggest challenge.

“It’s right there. So let’s take advantage of it.”

Games three and four will be played Saturday and Monday in Cleveland.

The winners will play either the Oklahoma City Thunder or the San Antonio Spurs, who are tied 1-1 in the Western Conference Finals.
