BOSTON — The fans showered former Celtic Kevin Garnett with chants, and Boston rained key 3-pointers on the Minnesota Timberwolves.

Kelly Olynyk scored 19 points, Jae Crowder had 18 and the Celtics beat the Minnesota Timberwolves 113-99 on Monday night while the crowd begged to see Garnett.

“Three-point shooting is probably the next most contagious thing to the flu,” forward Olynyk joked. “When one person knocks them down, they usually come in waves, so it’s good to get people going that way.”

Boston was 12 of 25 from behind the arc, two off its season high.

Tyler Zeller scored 14 points and grabbed eight rebounds before fouling out. David Lee had 13 points and eight boards to help Boston snap a three-game losing streak.

Minnesota coach Sam Mitchell said before the game that the 39-year-old Garnett would rest because it was the second of back-to-backs after the Timberwolves beat Brooklyn. The crowd loudly chanted “We want KG!” close to a dozen times.

“I definitely heard all the chants,” Garnett said.  “It meant a lot to me. I would like to say Minnesota made me a young man and I grew up when I came to Boston.”

Garnett signed a two-year deal with Minnesota over the summer, but this could have been his last game in Boston.
