Celtic edge Warriors 121-118 in OT

Celtic edged the Warriors 121-118 in finals rematch at TD Garden in Boston.

Jayson Tatum scored 34 points with a career-high 19 rebounds, following Horford's overtime 3 with one of his own to put Boston up by seven with 1:30 left. Jaylen Brown added 16 points, making a 3-pointer with 19 seconds left in regulation to send the game into overtime.

The victory snapped a four-game losing streak against Golden State — the last three games of the finals and the first regular-season rematch, which the Warriors won in San Francisco in December.

Jordan Poole had 24, Klay Thompson added 24, and Stephen Curry had 29 points for the Warriors before fouling out in overtime. The reigning champions' road record this year is now 5-18.

Before Brown's 3-pointer tied it, Boston had led by as many as 10 points in the first half but had fallen behind the entire second. The Celtics scored the opening four points of the overtime period, but the Warriors went ahead 111-110 when Draymond Green made a pair of free throws and Stephen Curry sank a 3-pointer.

With 1:26 left, Tatum's 3-pointer and Horford's 3-pointer gave the Celtics a 118-111 lead after Brown made a floater to regain the lead. Golden State had a chance to win at the buzzer after Boston made mistakes late in the game, but Poole's half-court attempt fell short.

The Warriors prevailed in the championship series' Game 6 in Boston before triumphing in the first regular-season rematch in San Francisco. Despite having the best record in the NBA thus far, the Celtics are still miffed about their losses to Golden State.

Tatum struggled against the Warriors in June, but on December 10 at Golden State, he scored 18 points on 6-for-21 shooting. However, he acknowledged that Horford, who had 10 points, five rebounds, and a chase-down blocked shot in the opening frame, was responsible for Boston's strong home performance.
