CLEVELAND: When Cavaliers coach Tyronn Lue vowed Tuesday that a lineup change was coming but didn’t give details, sitting on his decision may have been a ploy in itself.

At least it turned out that way Friday night in a 115-108 victory over the Indiana Pacers at Quicken Loans Arena.

Tristan Thompson, back starting at center for the first time since Nov. 1, before he missed 19 games with a serious calf injury, rewarded his coach by nearly recording a double-double in the first half. He finished with 10 points and 10 rebounds.

Lue wanted more rebounding with Thompson next to Kevin Love, back at his natural position of power forward and the two combined for 16 rebounds in the first 24 minutes and 23 for the game.

But the threat of losing his shooting guard spot seemed to light a fire under J.R. Smith, even though it didn’t happen.

Smith scored 12 points in the first quarter, making 4-of-6 from 3-point range.

He had not scored in double figures in the last seven games and had totaled just 33 points in that span.

Smith made a season-high seven 3-pointers, his most in a regular-season game since April 9, 2016, at Chicago, and finished with a season-high 23 points. He sank 8-of-15 from the field, including 7-of-13 from beyond the arc.

The Cavs also improved their ball movement, handing out 27 assists on 46 field goals.

Lue’s changes produced the Cavs’ fourth victory in their last 14 games and prevented the Pacers from sweeping the four-game season series for the first time since the 2012-13 season. The Cavs went 1-3 against the Pacers, a reverse of a year ago.

LeBron James, who became the seventh member of the NBA’s 30,000-point club on Tuesday, turned in his eighth triple-double of the season and 63rd of his career with 26 points, 10 rebounds and 11 assists.

But he also committed 11 — leading to 26 Pacers’ points — of the Cavs 21 turnovers, including a crucial one with 1:20 remaining and the Cavs up 111-106.

James sealed the game with a driving lay­up with 53.2 seconds to go and Kyle Korver added two free throws with 6.9 seconds remaining.

The Pacers, who were 7-3 in their previous 10 games, had held nine of their last 10 opponents to 32.1 percent shooting or less from 3-point range, but the Cavs connected on 13-of-37 (35.1 percent) from long distance.

The Cavs were without guard Dwyane Wade, who also missed shootaround while dealing with a personal matter. General Manager Koby Altman told Wade to take as much time as he needs.

Without the leader of the second unit, it was made up of Derrick Rose, Kyle Korver, Jeff Green, Jae Crowder and Channing Frye. Rose, just four games into his return from a sprained left ankle complicated by a bone spur, scored his most points (14) since Nov. 3 at Washington. He made 6-of-8 shots from the field in 15 minutes.

Frye had not played in three of the past five games and was inactive Tuesday in San Antonio with an abdominal strain.

The Cavs reserves totaled 34 points as Jeff Green added 11 points.

Not all of the Cavs’ issues during their post-Christmas slump were corrected. They committed several sloppy turnovers, including a blatant Isaiah Thomas toss in the direction of James in the third quarter.

Thomas was whistled for his fourth technical foul of the season (to go along with a flagrant 2 and ejection at Minnesota on Jan. 8) with 5:26 left in the third quarter. Thomas scored 12 points on 5-of-13 shooting.

But the Cavs, who opened Monday with a no-holds-barred team meeting at their practice facility, finally found some semblance of unity on the court.
