One of these days he will settle on the right combination.

Miami Heat coach Erik Spoelstra will use his fourth starting lineup in four games during Game 4 of an Eastern Conference semifinals series against the Indiana Pacers on Sunday.

Spoelstra will move center Ronny Turiaf into the starting lineup alongside forwards LeBron James and Shane Battier and guards Dwyane Wade and Mario Chalmers, according to SI.com.

Turiaf, 29, started five games for the Heat during the regular season after joining the team in March. He averaged 3.0 points and 4.1 rebounds this season.

In a Game 3 loss, Spoelstra trotted out seldom-used center Dexter Pittman alongside James, Battier, Wade and Chalmers. In a Game 2 loss, he used Turiaf, James, Wade, Chalmers and forward Udonis Haslem. 

In a Game 1 victory, Miami started Chris Bosh, James, Wade, Chalmers and Haslem. Bosh was lost in Game 1 due to an abdominal strain.

The Pacers hold a 2-1 series lead over the Heat.
