Klay Thompson scored 25 points, Daniel Gafford gave the Mavericks 15 rebounds in what could be his last start at center for a while and Dallas beat the Boston Celtics 127-120 on Thursday night in their NBA Finals rematch.

Klay Thompson scored 25 points and Spencer Dinwiddie added 22 off the bench as the undermanned Dallas Mavericks earned a 127-120 road victory over the Boston Celtics on Thursday in a matchup of teams that met in last year's NBA Finals.

The Celtics have the league’s best road record but continue to struggle at TD Garden, and on Thursday the shorthanded Dallas Mavericks dominated Boston, 127-120, to avenge last month’s loss in Dallas.

Klay Thompson scored 25 points as Dallas beat the Boston Celtics 128-120 on Thursday night in their NBA Finals rematch.

Their blockbuster offseason addition was Klay Thompson, the longtime sharpshooter who was initially thought to be the most ideal fit for a team headlined by Luka Doncic and Kyrie Irving. However, that same Doncic-led Mavericks group wasn’t the same team that returned to TD Garden for the first time since Game 5 of the Finals.
