BOSTON, (Reuters) – The Boston Celtics were able  to rest Paul Pierce, Kevin Garnett and Ray Allen for the final  quarter as they cruised to a convincing 122-103 win over the  Indiana Pacers.

Pierce led the Celtics with 20 points and Rajon Rondo had a  double-double, scoring 16 points and 11 assists before coming  off late in the third quarter.

“We played like a team on a mission,” Pierce told  reporters, “hopefully that will carry over for the rest of the  season.”

Replacements Glen Davis and Nate Robinson came off the  bench and each contributed 15 points for the Celtics, who were  playing their third game in four nights.

“When they (Davis and Robinson) play like that, the tone of  the game changes,” Celtics coach Doc Rivers said. “We’ve just  got to keep him (Robinson) aggressive.

Kevin Garnett was the only Celtic starter not to reach  double figures in scoring, leaving the game with nine points  late in the third quarter. None of the Boston starters played  more than 29 minutes in the victory.

The Atlantic Division’s top team led by six points at the  end of the first quarter and stretched it to 20 at halftime,  sparked by three consecutive three pointers by Robinson.

The victory snapped a two-game losing streak for the  Celtics, who were booed by their own fans after suffering a  20-point loss at home to the Memphis Grizzlies on Wednesday.

“We really had a heart-to-heart this morning,” Pierce said.  “It really left a bad taste in our mouth the way we played our  last game. Nobody wants to be booed at home by the home crowd.”

Roy Hibbert led the Pacers with 23 points and Danny  Granger, back in the lineup after serving a one game suspension  for fighting on Saturday, scored 16 points.

“We are playing a wounded tiger,” Pacers coach Jim O’Brien  said. “They came out and pounded us and we never recovered from  that.”
