BOSTON (AP) — Jayson Tatum scored 34 points with a career-high 19 rebounds, following Al Horford's overtime 3-pointer with one of his own on Thursday night to help the Celtics pull away from Golden State in an NBA Finals rematch and beat the Warriors 121-118. Jaylen Brown added 16 points and nine rebounds, making a 3-pointer with 18 seconds left in regulation to send the game into overtime. Horford had 20 points, 10 boards and three blocked shots for the Celtics, who lost to the Warriors in the NBA Finals in six games and then lost a fourth straight game to them in their first regular-season matchup in December.
