ATLANTA – Kent Bazemore sparked a stunning turnaround with three straight 3-pointers in the second quarter, and the Atlanta Hawks reclaimed the upper hand in their playoff series against the Boston Celtics with a 110-83 rout Tuesday night.

The Hawks are up 3-2 in the series and positioned to close it out Thursday in Boston. If Game 7 is needed, it would be Saturday in Atlanta.

This one started out horribly for Atlanta, which couldn’t make a shot and trailed 29-19 midway through the second quarter. Then, suddenly, the Hawks looked like an entirely different team.

Led by Bazemore, Atlanta ripped off a 28-8 run to take control before halftime. The Hawks totally blew it open with a 42-point third quarter, heading to the final period up 89-62.

Mike Scott led the Hawks with 17 points, while Bazemore and Jeff Teague added 16 apiece. Evan Turner topped Boston with 15 points.

The Hawks made only six of their first 34 shots, the sellout crowd’s groans and moans growing louder with each miss. But Boston wasn’t exactly lighting it up, either, missing a chance to build a bigger cushion.

Then, coming out of a timeout in which mascot Harry the Hawk did a tribute to Prince and the arena was aglow in purple, the Hawks found their shooting touch.

Boy, did they ever go crazy.

Atlanta ripped off 11 straight baskets, five of them from beyond the arc. Bazemore made three in a row, while Teague and Scott also connected from long range. Just like that, the double-digit deficit turned into a 10-point lead.

Even though the run finally ended with Teague missing a shot at the halftime buzzer, the Hawks went to the locker room up 47-39. They didn’t slow down a bit after the break, knocking down 16 of 26 shots (62 percent) in the third to make it a rout.

Celtics star Isaiah Thomas, who averaged 35 points in two victories at Boston that evened the series, managed only seven points on 3-of-12 shooting. He hobbled off to the locker room in the closing minutes with what was described as a mild left ankle sprain.

It wasn’t thought to be anything serious, but there was no need to come back in this one.

The Hawks got a chance to rest their starters, too. Little-used players such as Kris Humphries, Kirk Hinrich and Lamar Patterson closed out the game for the home team.

Humphries, playing in the series for the first time, even knocked down a couple of 3s.

Boos for Isaiah

Thomas was booed by the Atlanta crowd every time he touched the ball, the fans still mindful of an incident in Game 3 in which the guard took a swing at Atlanta’s Dennis Schroder.

The Boston star was assessed a Flagrant 1 foul but avoided a suspension when the league office reviewed the incident.

Courtside

Former Hawks owner Ted Turner was among those sitting in the front row for Game 5.

Atlanta Falcons stars Julio Jones and Devonta Freeman were also in the house, along with several of their NFL teammates.

Raptors 102, Pacers 99

TORONTO – DeMar DeRozan scored 34 points and the Toronto Raptors held on for a 102-99 victory over the Indiana Pacers and a 3-2 lead in their first-round series Tuesday night when Solomon Hill’s 3-pointer was ruled after the buzzer.

The Raptors overcame 39 points from Paul George and a 13-point deficit in the fourth quarter, getting 14 points from Kyle Lowry.

Bismack Biyombo had 10 points and 16 rebounds for the second-seeded Raptors, who can clinch the first seven-game playoff series victory in franchise history by beating the Pacers in Indiana on Friday night.

George Hill had 15 points and Myles Turner 14 for the Pacers, who led by as many as 17 and never trailed through the first three quarters before coming unglued in the fourth.

Jonas Valanciunas scored 11 and rookie Norman Powell had 10 for Toronto.

The Pacers made 13 of 29 from 3-point range but struggled from all over the floor in the fourth, making four of 15 shots and scoring just nine points in the period.

Trailing 90-77 to begin the fourth, the Raptors tied the game with a 15-2 run. Powell stole the ball from Monta Ellis and made a fast-break dunk to knot it at 92-all with 6:31 remaining, sending the sellout crowd of 19,800 into a frenzy.

Toronto’s first six points of the fourth came with George on the bench. He checked back in with 8:36 left.

After Powell’s basket, neither team scored again until DeRozan hit a tiebreaking 3 with 4:15 remaining. After a missed 3 by Ellis, Cory Joseph hit another 3 for Toronto, putting the Raptors up 98-92 with 3:26 left.

Solomon Hill’s 3 with 15.9 seconds cut it to 100-99, but DeRozan answered with a pair of free throws.

Indiana had the ball under Toronto’s basket with 2.7 seconds left. Ellis inbounded to George, who fed Solomon Hill, and Pacers players threw their arms up in celebration when his shot from the left side went through the net. But video replay confirmed that the shot came too late.

George scored 12 points in the first and the Pacers were 7 of 10 from 3-point range to lead 35-20 after one.

With George on the bench, the Raptors closed the gap with a 13-1 run to begin the second, making it 36-33. George returned and hit a 3 at 8:05, snapping a streak of seven straight missed field goals by the Pacers. George scored seven of the next 10 Indiana points before Toronto called timeout. DeRozan scored 13 in the second while George had 10 as the Pacers led 61-52 at halftime.
