INDIANAPOLIS — Indiana aced one major test Wednesday.

Now coach Nate McMillan expects the Pacers to continue putting up high marks.

Malcolm Brogdon scored 29 points and made all 15 of his free throws, the Holiday brothers combined for 20 fourth-quarter points and Indiana rallied from a 10-point deficit to finally beat the Boston Celtics 122-117.

“One of our problems all season has been closing out these games against elite teams," Brogdon said. "Tonight we were able to do that so it will definitely help our confidence.

The rebuilt Pacers snapped a seven-game losing streak against Boston, which included a first-round playoff sweep last season. They managed to dig themselves out of a 94-84 hole to start the fourth quarter with teamwork, defence and patience. And they did it with injured All-Star Victor Oladipo cheering throughout the stretch run.

The fact this performance came on a night three-time All-Star Kemba Walker scored a season-high 44 points, making seven 3-pointers and dishing out seven assists to lead Boston only made it sweeter.

“He's obviously one of the great players in the league and once he gets downhill, it's tough to stop him," Aaron Holiday said. “I just tried to fight over the screens and hoped my bigs could help me at the rim."

For McMillan, it was precisely the kind of effort he talked about Monday as the Pacers entered their most challenging three-week stretch so far.

And against an old nemesis in Boston, the Pacers played it perfectly.

They withstood Walker's 15-point first quarter, his scoring flurries at the end of the first half and start of the second half, even the 12-2 run Walker and Jayson Tatum spurred to close out the third quarter.

So with Walker on the bench, Indiana took advantage and turned the game with a team effort.

The Pacers forced five turnovers in the first 8 1/2 minutes of the fourth quarter to close to 98-96.

Doug McDermott finally tied the score at 102 with two free throws at the 5:07 mark. Aaron Holiday gave Indiana a 105-104 lead with 4:16 left and Justin Holiday added gave Indiana a 114-109 lead with 1:26 left. Brogdon made six free throws in the last 17.1 seconds and Walker fired an airball on a 3 that would have tied it with 4 seconds to go.

Boston's four-game winning streak ended.

“I just missed," said Walker, who was 2 of 7 in the fourth. “I took some good ones, maybe a few that weren't so good but I just missed."

BACK HOME AGAIN

Trips to Indianapolis are usually enjoyable for Boston coach Brad Stevens, who led nearby Butler to two Final Four appearances after growing up in Brownsburg — an Indianapolis suburb.

And he's far from alone.

Gordon Hayward also grew up on the west side of Indianapolis and played on Butler's first Final Four team. Rookie guard Carsen Edwards starred at Purdue and rookie guard Romeo Langford was the state's 2018 Mr. Basketball Award winner. He played at Indiana University last year and had a large group of supporters make the trip from his southern Indiana hometown, New Albany, for the game.

OLADIPO UPDATE

McMillan said Oladipo looks better in practice and continues to make progress, but there's still no timetable for his return from a ruptured quad tendon in his right knee.

He suffered the injury in January.

“He's still rehabbing, working hard and he's certainly getting better," McMillan said. “He's getting closer but I think he's still a ways off."

UP NEXT

Celtics: Head home for their second showdown this season with division rival Philadelphia on Friday.

Pacers: Will try to extend their winning streak over the Hawks to six straight Friday in Atlanta.
