Kevin Garnett  led all five Celtics  starters in double-figure scoring with a season-high 27 points and powered a key run at the start of the fourth quarter as the Celtics outlasted the Raptors, 99-93, Wednesday night at Air Canada Centre  in Toronto. His turnaround jumper with 46.6 seconds left put Boston up 96-91.
Garnett’s three-point play with 8:46 remaining capped a 10-0 run at the start of the final period as the Celtics overcame a sloppy third quarter to win their fifth straight game and improve to 25-23 on the season. Garnett was 11-of-18 from the field and added 10 rebounds in the win.
Paul Pierce  had 12 points and 11 rebounds while former Raptor Leandro Barbosa  chipped in 14 points off the Boston bench. Courtney Lee  (15), Avery Bradley  (11) and Brandon Bass  (10) also scored in double figures. After dominating the previous four games, the Celtics bench was not a major factor Wednesday but still outscored Toronto’s reserves, 24-20.
The Celtics finished the first half on an 11-6 run to take a 50-45 lead. The Celtics scored first in the third quarter to increase their lead to seven, but Rudy Gay  then came alive. Gay, who was 8-of-22 from the field, scored 13 of his team-leading 25 in the third.
The Raptors appeared ready to steal the game with a 17-4 run late in the third quarter. The Raptors would outscore the Celtics 34-19 to take a 79-69 lead heading into the final 12 minutes. The Raptors had five of their 11 steals in the quarter as Toronto took command.
But Garnett led a Celtics charge that saw Boston outscore Toronto 30-16 in the final 12 minutes to wrap up a fifth straight win. Barbosa had 12 of his 14 in the final period to help Garnett and the Celtics put the game away.
The Celtics will have little time to rest as they fly back to Boston and take on Kobe Bryant  and the Lakers on Thursday at 8 p.m. at TD Garden. The Lakers will not have the services of Pau Gasol , as the Lakers big man was diagnosed with a torn plantar fascia .
