Jayson Tatum scored 22 points, Derrick White added 20 and the Boston Celtics showed their championship makeup down the stretch with a 112-105 win over the Cleveland Cavaliers in a matchup of the Eastern Conference’s top teams.

Derrick White scored 14 of his 20 points in the fourth quarter to help the visiting Boston Celtics extend their winning streak to four games with a 112-105 victory over the Cleveland Cavaliers on Tuesday night.

With just days until the All-Star break and a series of uneasy fourth quarters in recent games, Boston could have faltered. But it was sharp defense that carried them over the best in the East.
