Domantas Sabonis just knocked down a huge game-winning bucket to seal the Indiana Pacers' win over the visiting Boston Celtics on Sunday.

The one-time All-Star came up big once again and tallied his third-straight double-double with 19 points and 10 rebounds en route to the Pacers' third-straight victory.

Domantas Sabonis' late bucket gave the Pacers a one-point lead with under 10 seconds to go in the ball game. He was fouled on the play and had a chance to convert the 3-point play on the line but failed to do so. The Celtics had a chance to win the game in their last possession, but Jayson Tatum missed a last-second three that ultimately sealed Indiana's win.

The 24-year old Lithuanian-American entered his fifth year in the league with high expectations. After making his first All-Star selection last year, Sabonis is poised to have an even bigger year as the Pacers' focal point on offense. After three games, Sabonis has averaged 24.3 points, 11.0 rebounds and 7.0 in 37 minutes of action. He also grabbed his first triple-double of the season against the Chicago Bulls prior to Sunday's game against Boston.

Sabonis' game has slowly evolved as he tried to be the superstar the Pacers need him to be. Aside from being a force in the paint, the Oregon native has also added range to his jumper and has shot 4-of-9 from deep so far this season. He also showcased his ball-handling ability on Sunday, as he drove past two Celtics defenders for the game-winning bucket.

It has just been three games, but from the looks of it, Sabonis is poised to have a monster campaign.
