Mikal Bridges saved his best for last again, blocking Jayson Tatum from behind in the closing seconds as the Knicks overcame a 20-point deficit in the third quarter for a second straight game in Boston to grab a 2-0 series lead with a thrilling 91-90 Game 2 win at a stunned TD Garden.

Bridges, the overtime hero in Game 1 two nights earlier, also scored all 14 of his points in the fourth for the Knicks, who will return home to a raucous MSG for Game 3 on Saturday.

Josh Hart led the Knicks with 23 points and Karl-Anthony Towns added 21 with 17 rebounds.

Brunson also made up for a 6-for-19 shooting night with nine of his 17 points in the fourth quarte, including two free throws to put the Knicks ahead with 12.1 seconds remaining.

Brunsonw was fouled with 12.7 seconds left and calmly sank both free throws. Knicks by one.

Tatum just went coast to coast off the inbounds pass and drove around Robinson for the go-ahead dunk with 18.1 seconds on the clock.

Two free throws by Tatum and a missed trey from Brunson gives the Celtics the ball down by one, 89-88, with 24.2 ticks remaining. Another crazy postseason game for the Knicks.

The Knicks' D has caused the Celtics to miss 14 straight shots, and Brunson nails an elbow jumper for the Knicks' first lead of the game.and follows with a transition layup for a 3-point Knicks lead in the final minute.

Bridges long 2-pointer a couple of minutes ago was switched to a 3, and the Knicks suddenly are within four with under three minutes left. Towns follows with a traditional three-point play and that 20-point deficit is now one with under 2:00 to go.

It's 13-2 now after a Brunson trey and a Hart teardrop sandwiched around another clanked 3 by Tatum. Five-point game, final three minutes. Buckle up, kids!

Bridges just nailed a long 2-pointer to cap an 8-0 run, and the Knick have clawed back within eight with under 6:00 to play.

With Towns and Brunson getting a rest to start the fourth, Porzingis threw down an and-1 dunk and two Pritchard bombs expanded the lead to 16. Bridges finally has his first points, with seven already in the fourth, but Robinson just badly air-balled a free throw.

Also, Hart just came out, possibly with that hand/wrist issue.

Can they do this a second straight game? Down 20, the Knicks have scored the last eight, including 3s by McBride and Hart to draw within 73-61 in the final minute of the third.

Boston held for the final shot, a miss by Brown, and the Knicks trail by a dozen entering the final period.

Porzingis finally made an impact with a dunk and a 3 for his first points of the series to push the Boston advantage to 20.

Anunoby skied through the lane for a one-handed dunk, but he also slammed into White on the play and was called for the charge.

Towns also picked up his third foul, and the Knicks need to stop the bleeding again, down a game-high 18 with 4:36 left in the third. An 11-2 spurt since the OG dunk was overturned.
