The Boston Celtics defeated the Oklahoma City Thunder, 135-100, at TD Garden on Wednesday night.

The Celtics (60-16) knew they were already coming in with a significant advantage due to the absences of Shai Gilgeous-Alexander (quadriceps) and Jaylen Williams (ankle), but they didn't rest on their laurels. Boston had already built a 61-47 lead after an aggressive first half, but the Thunder (52-24) was able to put a four-point dent in their deficit in the third quarter to make things interesting. However, that only served to sharpen the hosts' focus, as they dominated OKC by a 42-17 margin over the final 12 minutes to notch the runaway victory and clinch home-court advantage throughout the playoffs.

Josh Giddey led the Thunder with 17 points, adding six rebounds and two assists. Luguentz Dort furnished 15 points, five rebounds and one block. Isaiah Joe delivered 13 points, three boards, one steal and one block. Cason Wallace supplied 12 points, five assists, one rebound, four steals and one block. Chet Holmgren totaled 11 points, seven rebounds and two assists. Aaron Wiggins registered 10 points, five assists, one rebound, one steal and one block.

Kristaps Porzingis paced the Celtics with a 27-point, 12-rebound double-double that included four assists, five blocks and one steal. Jayson Tatum recorded 24 points, seven rebounds, three assists and one steal. Jaylen Brown managed 23 points, seven boards, four assists, two blocks and one steal. Al Horford compiled 16 points, four rebounds, two assists and one block. Jrue Holiday finished with 12 points, seven rebounds, four assists and one block. Payton Pritchard offered 11 points, eight assists, four rebounds and two steals. Sam Hauser netted 10 points.

The Thunder remain on the road and visit the Indiana Pacers on Friday night, while the Celtics host the Sacramento Kings on Friday night as well.
