INDIANAPOLIS — Isaiah Thomas fought through an off-shooting night, then came through for the Boston Celtics when it mattered most.

Thomas scored 23 points, including Boston’s final eight, to lead the visiting Celtics past the Indiana Pacers 105-99 on Saturday night.

“Isaiah did a lot for our team tonight even though he wasn’t shooting well,” Avery Bradley said of his teammate’s 12-point fourth quarter. “That’s what the game is all about, the fourth quarter.”

Thomas had just four points through 34 minutes before scoring 19 over the final 14 minutes. He hit several clutch shots to keep Indiana at bay and sealed the win at the foul line in the final 30 seconds.

With all-star Paul George sitting out the game because of a sprained left ankle, the Pacers needed the help Thomas was affording them. After starting hot, the Pacers looked as if they wouldn’t miss their leading scorer.

In the first half, Indiana was crisp on offense, moving the ball, spacing the floor and getting the shots they wanted. But after halftime, they cooled off from the field and looked scattered at times on both ends of the floor.

Boston lingered, and all they needed was Thomas to get involved.

With his team struggling to seize control of a tight contest, Thomas surged in the fourth quarter. Boston was nursing a 91-89 lead with 4:04 left before Thomas calmly hit a floater in the lane. After Monta Ellis hit a free throw to pull Indiana within 97-94 with 1:31 left, Thomas hit a pair of free throws, scored on a fast-break layup with a minute left, and then added four free throws to seal Boston’s second road win of the year.

Pacers Coach Nate McMillan said his team didn’t challenge Boston in the final minutes to play to Indiana’s strengths.

“We want to make teams defend, get to our second, third, fourth option,” McMillan said. “You don’t win games when you don’t make plays down the stretch.”

Kelly Olynyk scored 16 points for the Celtics, who were playing the first of two straight road games. Amir Johnson scored 14 and grabbed nine rebounds, while Bradley added 13 points and five assists.

Jeff Teague led Indiana with 20 points and four assists. Myles Turner scored 17 and had eight rebounds. Ellis notched 15 points in the Pacers’ first home loss of the season.
