Jayson Tatum scored a game-high 35 points to help the Boston Celtics clinch their Eastern Conference first-round playoff series with a 120-89 Game 5 victory over the visiting Orlando Magic yesterday (Philippine time).

Tatum was 10-of-16 from the field and made all 11 of his free-throw attempts while adding eight rebounds and 10 assists as the Celtics wrapped up their first-round series in five games for the second year in a row.

Jaylen Brown added 23 points for the Celtics, who outscored the Magic, 73-40, in the second half.

The Magic lost their sixth consecutive first-round series — dating back to 2010-2011 — despite 25 points from Franz Wagner. Paolo Banchero collected 19 points, nine rebounds and six assists. Wendell Carter, Jr. added 12 points and 10 rebounds.

Second-seeded Boston took control after Banchero went to the bench after being called for his fifth foul with 9:46 remaining in the third quarter.

It was 53-53 at the time, but the Celtics outscored the seventh-seeded Magic, 36-13, in the third and owned an 83-62 advantage entering the fourth.

Boston had a 24-4 run in the third quarter.

Orlando had a 15-3 edge in offensive rebounds, but shot 8-of-38 from three-point territory.

The Magic shot 37.5 percent from the field in the game (33-of-88).

The Celtics didn’t make a three-pointer until Tatum connected with 10:22 left in the third quarter, but they made 13-of-24 three-point attempts overall.

Boston was 43-of-76 from the field (56.6 percent) in the game.

Boston was again without guard Jrue Holiday, who missed his third straight game with a strained right hamstring.
