BOSTON -- Jason Richardson bounced back from his worst game of the season to score 34 points with 10 rebounds, and the Phoenix Suns rebounded from their only defeat to beat the Boston Celtics 110-103 on Friday night.

Kevin Garnett had a season-high 26 points for Boston -- the most he's scored since missing the end of the 2008-09 season and the playoffs with strained ligaments in his right knee.

Steve Nash had 16 points with 12 assists for Phoenix, shaking loose to hit a 3-pointer with 51 seconds left after Boston closed an 11-point fourth-quarter gap to four points. Amare Stoudemire added 22 points, while Richardson finished 6 for 7 from 3-point range.

Boston was trying to start 7-0 for the second time in three years. The Celtics won their first eight games in 2007-08 -- and first 13 at home -- en route to their record 17th NBA title.

Rajon Rondo scored 14 with 11 assists, and Paul Pierce and Ray Allen each scored 16 points for Boston.
