BOSTON (AP) — Kyrie Irving had 19 of his 32 points in the second half, helping offset a 40-point night by Giannis Antetokounmpo as the Boston Celtics held off the Milwaukee Bucks 111-100 on Monday night.

Al Horford added 20 points, nine rebounds and eight assists. Jayson Tatum chipped in 17 points to help Boston improve to an NBA-best 21-4. The Celtics have won five of their last six.

It was the third 40-point game this season for Antetokounmpo. Khris Middleton added 19 points while Eric Bledsoe had 18 points.

Boston led by as many as 20 in the third quarter, before the Bucks stormed back, thanks in large part to Antetokounmpo. He almost singlehandedly kept the Bucks in it, scoring 16 points in the period and trimming Boston’s lead to 88-81 entering the fourth.

It was 104-97 following a free-throw by Bledsoe, but the Celtics got five straight points from Irving to get the lead back up to 12 with less than a minute to play.

Antetokounmpo and Middleton entered Monday as the most productive scoring duo in the Eastern Conference, averaging a combined 49 points per game.

They combined for 59 Wednesday. It offset some early inconsistency from the rest of their teammates, which went just 6 of 24 from the field in the first half.
