BOSTON, Feb. 1 (Ticker) -- Terrell Brandon scored six of his 21 points in overtime as the Minnesota Timberwolves rallied for a 98-95 victory over the slumping Boston Celtics.

Kevin Garnett also scored 21 points for the Timberwolves, who have won four straight visits to the FleetCenter dating to January 2, 1998. Overall, Minnesota has won seven of its last nine games against Boston.

Brandon scored 51 seconds into the extra session to give the Timberwolves the lead for good, 87-85. Overall, the 5-11 guard shot 7-of-13 from the field and hit all seven of his free throws.

"(It was a) big win," said Brandon, who had nine rebounds and nine assists. "They're a very explosive team, particularly with their two All-Stars. But we stayed patient."

Minnesota shot 20-of-25 from the line and was successful on 13-of-14 in the fourth quarter and overtime.

"If you put it in Brandon's hands, you're going to have a pretty good chance of making them (free throws)," Timberwolves coach Flip Saunders said.

"When we get on the line, we knock them down," Minnesota guard Chauncey Billups said.

Boston lost 97-92 in Toronto on Thursday.

All-Star Paul Pierce scored 22 points and Kenny Anderson added 21 for the Celtics, who have lost three in a row for the first time since dropping four straight from November 17-24.

Billups' layup made it 89-85 with 3:34 remaining, but Pierce completed a 3-point play 18 seconds later.

Erick Strickland had a chance to give the Celtics the lead with just under three minutes to play but missed a dunk that bounded to Kenny Anderson at the top of the circle. Anderson missed a jumper and Wally Szczerbiak hit a 3-pointer at the other end, making it 92-88.

Szczerbiak followed just under a minute later with a 15-footer from the right side, giving Minnesota a six-point cushion.

"You just have to turn it on and hit a three and a post-up in overtime," he said. "But that's what I'm paid to do."

Eric Williams hit a 3-pointer with 8:07 left in the third quarter to give the Celtics their biggest lead, 55-44. But the Timberwolves scored 17 of the next 28 points, pulling within 66-61 at the end of the quarter on Brandon's 17-foot jumper with just two seconds left.

Minnesota trailed for most of the fourth quarter until Billups hit a 3-pointer with 3:25 left for an 80-78 lead.

"I saw Erick and someone else looking around at who to pick up," Billups said. "And I was at the top of the key and just shot it."

Boston's Tony Battie had a tying free throw with 35 seconds to go and a dunk that forced overtime with eight seconds left.

"One of the things that we have to work on tomorrow as a team is when we get up on a team, to maintain that lead and then to finish them off at the end," said Boston All-Star forward Antoine Walker, who scored 13 points on just 4-of-20 shooting.

"For some apparent reason in the last three or four ballgames, we haven't been able to close it out," Walker added. "We're not playing 48 minutes of basketball."
