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.

Tatum and Jaylen Brown played the entire second half as Boston fought back against a feisty Philadelphia squad that shot 46.9 percent from 3-point range without three usual starters including Joel Embiid and Paul George. Ultimately, Boston’s hot shooting and improved defensive intensity turned the game around after Mazzulla’s halftime speech.
