Jayson Tatum had 25 points, 10 rebounds and nine assists and five other players scored in double figures as the Boston Celtics advanced to the Eastern Conference finals for the third straight season with a 113-98 victory over the depleted Cleveland Cavaliers.

Al Horford added 22 points, 15 rebounds and six of Boston’s 19 3-pointers to notch their third consecutive win of the series in Game 5.

Derrick White had 18 points with four 3s and Jrue Holiday scored 13 for the Celtics, who will next face either Indiana or the Knicks, with New York currently leading that series 3-2.

Evan Mobley scored a playoff career-high 33 points and Marcus Morris Sr. added 25 with five 3s for the Cavaliers, who played without All-Star Donovan Mitchell (calf), center Jarrett Allen (rib) and key reserve Caris LeVert (knee).

Cleveland pulled within 88-85 early in the fourth on Mobley’s dunk, but Boston took control with a 13-2 run that was capped by Tatum’s 3.

Doncic helps Mavericks to 3-2 lead

Luka Dončić had a 31-point triple double and the Dallas Mavericks defeated the Oklahoma City Thunder for a 3-2 lead in the Western Conference semifinals.

Doncic shot 12 of 22 from the field and had 11 assists and 10 rebounds for his sixth career playoff triple-double. He averaged 22 points on 39 percent shooting through the first four games of the series.

Derrick Jones Jr. added a playoff career-high 19 points and P.J. Washington had 10 points and 10 boards for Dallas, which shot 52.6 percent from the floor and had a 46-33 rebounding advantage.

The Mavericks can advance to the West finals with a win on Saturday at home.

Shai Gilgeous-Alexander scored 30 points for the top-seeded Thunder, but no teammate had more than 13 points.

Dallas extended to an 18-point lead early in the fourth quarter, but Oklahoma City cut the deficit to 90-83 on Chet Holmgren’s dunk with 5:17 remaining. But Washington hit a 3 and then dunked to put the Mavs up by 10 and the Thunder never got closer than nine thereafter.
