BOSTON — Isaiah Thomas scored 17 of his 35 points in the fourth quarter, and the surging Boston Celtics beat the Charlotte Hornets 108-98 on Monday night for their ninth victory in 11games.

It was Thomas’ 25th straight game with 20 or more points. He’s been putting up big final quarters of late – scoring 20 or more three times this season. No other NBA player had done it more than once entering Monday.

Al Horford had 22 points, while Kelly Olynyk and Jae Crowder added 15 apiece for Boston, which has won all three meetings with Charlotte this season.

Kemba Walker scored 24 points and Marvin Williams had 21 for the Hornets, who lost their fifth straight – all on the road.

Thomas scored 13 straight points, pushing Boston ahead 93-83 with his 3-pointer from the left wing with 7½ minutes left.

Boston led 80-71 entering the final period.

Celtics rookie Jaylen Brown addressed the crowd before the game on Martin Luther King Jr. Day. Without notes, he quoted King in saying: “The day our lives begin to end, the day we become silent about things that matter.”
