Jayson Tatum had 33 points and 12 rebounds and Jaylen Brown added 28 points as the Boston Celtics rode a bounce-back performance for a 106-93 victory over the Cleveland Cavaliers on Saturday to take a 2-1 lead in the Eastern Conference semifinals.

After losing Game 2 at home by 24, the top-seeded Celtics looked more like themselves on Cleveland’s home court.

Tatum opened the second half with a three-point play to ignite a 14-0 run that gave Boston a 71-48 lead.

The Cavaliers got the deficit down to nine three times in the fourth quarter, but back-to-back 3-pointers from Payton Pritchard and Derrick White midway through the period ended any hope of a comeback.

Donovan Mitchell scored 33 points for Cleveland, but aggravated a left knee injury in the fourth quarter and was laboured. With Boston up 13 with 1:19 left, he left the court and walked directly to the locker room.

Evan Mobley added 17 points and nine rebounds for the Cavaliers, who had won their first four home playoff games. They haven’t won consecutive postseason contests since taking the first two against Orlando in the first round.

Cleveland was again without starting center Jarrett Allen, who missed his sixth straight game with a painful rib injury.

Boston center Kristaps Porzingis missed his fourth consecutive game with a calf strain.

Mavericks take 2-1 lead on Thunder

Kyrie Irving hit a running left-hander in the lane in the final minute and scored 22 points as the Dallas Mavericks held on for a 105-101 victory over the visiting Oklahoma City Thunder for a 2-1 lead in the Western Conference semifinals.

Luka Dončić also had 22 points to go with 15 rebounds and P.J. Washington added 27 points, two shy of his playoff high from the previous game.

Shai Gilgeous-Alexander tallied 31 points, 10 rebounds and five blocks as the top-seeded Thunder lost their second straight after opening 5-0 in the playoffs.

Game 4 is Monday night in Dallas.

Chet Holmgren had 13 points and four of the Thunder’s 11 blocks, but Oklahoma City was outrebounded 16-5 on the offensive glass and outscored 16-9 in second-chance points.

Irving bounced back from scoring nine points in Game 2 with 14 points in the second half alone, including six consecutive Dallas points in the fourth quarter that helped the Mavs to their biggest lead of the final period at nine.

Oklahoma City decided to foul Dereck Lively II intentionally in the fourth quarter, and he missed three of the first four free throws before he hit the next four in a row to put Dallas up 100-95 with 3:06 left.

After Gilgeous-Alexander made two free throws, Irving’s basket restored the Mavericks’ five-point lead.
