Rajon Rondo was there in the flesh, and his teammates showed up in force.

Behind contributions from all over, from their captain to a forward that joined the team midseason from China, the Celtics shot the lights out at TD Garden and thoroughly routed Atlanta, 118-107, on Friday night.

Boston won its second straight game overall as Rondo, its All-Star point guard, returned to the bench for the first time since his season ended with a knee injury.

The 118 points tied the Celtics’ season high; they scored that many in a triple-overtime win against Denver on Feb. 10.

Overall, the Celtics shot 53 percent (45 of 83) and made 11 of 23 shots from beyond the arc.

The Celtics received a huge boost from Jeff Green, who scored a game-high 27 points two days after making a game-winning layup in Cleveland.
