Jrue Holiday is happy to do things the hard way occasionally after helping the Boston Celtics survive a fightback from the Indiana Pacers.

The Eastern Conference-leading Celtics battled to a 129-124 victory at TD Garden on Tuesday to go 37-11 for the season.

Indiana rallied from 20 points down late in the first half to make it 127-124, but big back-to-back stops kept the Celtics' lead intact.

Holiday saw out the victory for his side with two free throws and has no complaints about being made to sweat for the win.

"We've got to be able to fight through everything," he said. "Fight through expectations, fight through being up 20.

"Fight through somebody having a great third quarter and finishing games. If it was easy the whole time, what's the fun in that?"

Jayson Tatum scored 30 points and came up with two blocks in the final 30 seconds as the Celtics made it five wins in six games.

Jaylen Brown also impressed with 25 points, while Derrick White added 24 for Boston, who claimed the season series with Indiana 3-2.

"You have to be able to win games with your defense," coach Joe Mazzulla said.

"It's a tough balance for us because we always talk about how the game's connected. You can't have one without the other.

"But there's moments when they both have to be elite. We had really good defense down the stretch and made some winning plays."

Aaron Nesmith had 26 points and 12 rebounds and Pascal Siakam added 23 as Indiana, who had won three in a row, fell short of a comeback.

"We got outplayed in the second half, for sure," Brown said. 

"But when it came down to it in the wire, fourth quarter, we were able to nudge out and win just by matching the physicality. 

"We rebounded better in the fourth quarter, a lot better than we did all game, and then that just helped us win."

The Celtics, boasting the best record in NBA, face the Los Angeles Lakers on Thursday. The 27-21 Pacers meet the New York Knicks the same day.
