The Knicks punched back in Game 3 at home, cruising past the Cavaliers 99-79 on Friday to take a 2-1 series lead.

Madison Square Garden was raucous for the Knicks’ first home playoff game in two years, and the two teams return to the arena for Sunday’s pivotal Game 4 clash.

RJ Barrett broke out of his early-series struggles in Game 3, recording 19 points on 8 of 12 shooting from the field.

Jalen Brunson erupted late in the game, pouring in a team-high 21 points along with six assists.

The Cavaliers answered the Knicks’ Game 1 victory with a blowout win of their own in Game 2, and will look to again rebound following another disappointing loss in order to even up the series.
