BOSTON — Former New Albany standout Romeo Langford had 7 points, 3 rebounds, 2 assists and a blocked shot and his Boston Celtics knocked off defending World Champion Milwaukee 117-103 on Monday evening at the TD Garden.

Langford went 3 for 7 from the field and made one of his four 3-point attempts as Boston improved to 14-14 on the season. The Bucks are now 18-11, third-best in the Eastern Conference. The Celtics are currently ninth in the Eastern Conference standings.

Langford’s layup with 2:36 left in the first quarter cut Milwaukee’s early lead to 25-21. The Bucks led 30-21 after one quarter, but Langford scored in the middle of a 27-17 run that gave the Celtics a 51-50 halftime lead.

With 2:56 left in the third period, Langford knocked down his 3-pointer to put Boston on top 79-68.

Jayson Tatum had a big night for the Celtics with 42 points. He was 16 for 25 from the floor and made 7 of his 13 3-point attempts. He also had 5 rebounds, 4 assist and 3 steals. Grant Williams scored 17 points — on just 7 field goal attempts — and grabbed 7 boards in 29 minutes off the Celtics bench.

Reigning NBA MVP Giannis Antetokounmpo and Jrue Holiday scored 20 apiece for the Bucks, who made just 40 of their 90 field goal attempts (44.4 percent) and just 11 of their 36 3-point attempts for 30.6 percent.

Langford and the Celtics host the Golden State Warriors in their next game Friday at 7:30 p.m. The game will be televised on ESPN. The Warriors are 22-5 — second in the Western Conference — after Monday’s 102-100 win over the Pacers in Indianapolis.
