BOSTON, (Reuters) – The Boston Celtics swept to a  confidence-boosting 119-93 win over the Detroit Pistons on  Monday, quickly returning to form after losing to conference  rivals Cleveland a day earlier.

The Celtics (42-24), coming into the game on the back of  three defeats in four, cruised to a 64-35 halftime lead and  were able to rest most of their starters for the fourth  quarter.

Kevin Garnett had 14 points and eight rebounds while Paul  Pierce and Ray Allen both scored 15.

“We have been talking and talking. At some point it’s time  to show some actions,” Garnett told reporters. “I’ll take it  though, hands down night and day, as far as yesterday (in  Cleveland) till today.”

Will Bynum had 16 points and seven assists for the woeful  Pistons (23-44), who were beaten for the ninth time in 11  contests and lost forward Tayshaun Prince in the first quarter  to a back injury.

Detroit has suffered injuries to key players for most of  the season and appears certain to miss out on the playoffs for  the first time since the 2000-01 campaign.

The Celtics are trying to return to their championship form  of two seasons ago but appear to be slowing with an aging  roster. Boston is just 19-19 overall since Christmas Day and  have made a few trades in an attempt to rejuvenate the team. Veteran acquisition Michael Finley, who was signed on March  6, contributed 15 points for his best game with his new squad.

“I didn’t know what to expect, honestly,” Boston coach Doc  Rivers said.

“He hadn’t played a lot this year with San Antonio and he  wasn’t making shots. I just don’t believe a guy can forget how  to shoot. So we thought if we could get him in here and get him  some looks… they would go in.”

In a dominating effort, every Celtics player in action  managed to score and the home team shot 62 percent from the  field.
