Jarrett Allen scored 14 of his career playoff-high-tying 22 points in the third quarter and grabbed 19 rebounds, powering the Cleveland Cavaliers to a 114-102 win over the visiting Toronto Raptors in Game 7 of their Eastern Conference first-round series Sunday night.

Fourth-seeded Cleveland, which trailed by double digits in the first and second quarters, will play the top-seeded Detroit Pistons in the East semifinals, beginning Tuesday in Detroit. The home team won every game in the Cavaliers-Pistons series.

Donovan Mitchell also had 22 points and James Harden posted 18 points and six rebounds for the Cavaliers, who built a 94-72 lead early in the fourth. Allen had 10 rebounds -- five offensive -- in the third when Cleveland outscored the Raptors 38-19.

Scottie Barnes collected 24 points, nine rebounds and six assists for fifth-seeded Toronto. RJ Barrett had 23 points on 9-of-25 field goal attempts and Jamal Shead added 14 points and seven assists.

Cleveland is 5-0 all-time at home in Game 7 and has beaten the Raptors all 11 times in the playoffs in its arena. The Cavaliers also have won all four of their postseason series against Toronto.

Evan Mobley, who had 13 points, scored the first basket of the second half to give Cleveland its initial lead at 51-49. It turned into a 20-2 run spanning the second and third quarters when Mitchell made a hoop with 9:28 remaining in the third to make it 58-49.

Cleveland used an 11-2 run to close the opening half, tying the score for the first time at 49-all on a Jaylon Tyson 3-pointer. Shead and Barnes led all players at the half with 14 points apiece, while Harden had 10 points and Sam Merrill added eight off the bench.

The Cavaliers committed 13 turnovers in the first half, which Toronto turned into 14 points. Cleveland had six miscues in the first quarter and seven in the second.

Barnes netted the first five points of the evening after Allen missed a dunk on Cleveland's opening possession. Shead made a runner to give the Raptors a 22-12 advantage, but Merrill had five points in the final three minutes to cut it to 26-24.

Shead scored seven points in the period and Barnes had five points and four assists, helping Toronto shoot 55% from the floor.

The Raptors were without two starters, small forward Brandon Ingram (right heel soreness) and point guard Immanuel Quickley (right hamstring strain).
