MINNEAPOLIS (AP) _ Paul Pierce scored a career-high 42 points to lead the Boston Celtics to a 107-102 victory over the Minnesota Timberwolves on Monday.

Pierce shot 15-of-22 from the field, and got past the Minnesota defense for a layup with 1:38 to play to give Boston a 100-98 edge _ its first lead of the fourth quarter.

Kevin Garnett missed two jumpers in the final 90 seconds, including a 3-pointer. Randy Brown then converted two free throws with 28.4 seconds to put Boston up by four. Pierce put the game away with two free throws with 22.3 seconds to play.

Boston won on the road for just the fourth time in 15 games this season.

Chauncey Billups and LaPhonso Ellis came off the bench to ignite a second-half rally that put the Timberwolves in the lead for most of the fourth quarter. Garnett led Minnesota with 23 points.

Billups scored 16 points and Ellis added 15 for Minnesota, which trailed for most of the third quarter but rallied to tie the Celtics at 76-76 after three quarters. The Wolves opened the fourth quarter on a 16-8 run, but Pierce scored 11 points in a 23-10 Celtics' run to close the game.

Minnesota's bench outscored Boston's 46-19.

Pierce's performance helped offset Antoine Walker's 6-for-26 shooting. Walker did finish with a triple-double with 20 points, 12 rebounds and 12 assists.
