San Antonio had nowhere to turn without its biggest star.

With Tim Duncan sidelined by a leg injury, the Spurs struggled down the stretch and lost 81-80 at home to the Memphis Grizzlies on Monday night. The Spurs made only one field goal in the final 9 minutes and 27 seconds.

And while they lauded Memphis' defense, it was clear that Duncan's absence was a huge factor.

``We have to give them credit, though for the great defensive pressure,'' said Manu Ginobili, who finished with 15 points and a career-high nine assists. ``We stopped moving the ball. ... There was no movement, so we couldn't take open shots.''

The Grizzlies, meanwhile, had a 14-point rally in the fourth quarter and won it on Lorenzen Wright's putback with 19.2 seconds remaining.

``I wanted to be aggressive and go after the loose ball and get the rebound,'' Wright said. ``Then, the ball ended up in my hands and I went back up strong.''

Elsewhere, it was Boston 117, Orlando 96; Utah 94, Detroit 86; Washington 111, New Orleans 106 in overtime; and Chicago 92, Cleveland 81.

The Grizzlies' strong defensive made the difference. On San Antonio's final two possessions, Memphis had its best defensive stands.

First, the Grizzlies forced point guard Jason Hart into a shot-clock violation with 28.9 seconds left. After Wright's putback, Memphis' suffocating defense made it hard for the Spurs to get off a final shot. Malik Rose drove the baseline in the waning seconds, but he took his shot while falling backward. It hit off the front of the rim and Memphis' James Posey hustled for the rebound as time expired.

Earl Watson led the Grizzlies with 13 points.

``Earl Watson was key,'' Shane Battier said. ``He really did single-handedly turn the momentum of the game in our favor.''

Hedu Turkoglu paced San Antonio with 19 points. Rasho Nesterovic added 18 and 10 rebounds.

Celtics 117, Magic 96

At Boston, Mark Blount had career highs of 28 points and 21 rebounds _ the Celtics' first 20-20 game in 10 years.

Boston scored the first 25 points of the fourth quarter and won its third consecutive game. Blount had his fifth consecutive double-double, Paul Pierce scored 25 points with nine assists for Boston.

Tracy McGrady, the NBA's leading scorer, had 29 points for Orlando after playing just two minutes in the first quarter because of foul trouble.

Jazz 94, Pistons 86

At Salt Lake City, Reserve Gordan Giricek scored 24 points in Utah's fourth straight win. Giricek had his best game since coming to the Jazz in a trade from Orlando for DeShawn Stevenson six games ago. Giricek made 10 of 17 shots, including all four of his 3-point attempts.

Rasheed Wallace scored 27 points in his best outing since arriving from Portland.

Wizards 111, Hornets 106, OT

At Washington, Gilbert Arenas scored eight of his 35 points in overtime, and the Wizards recovered after blowing a 21-point second-half lead.

The Wizards scored more points in the five-minute overtime (15) than they did in the entire fourth quarter (10).

Baron Davis scored 18 of his 33 points in the fourth quarter and overtime, and added 11 assists for the Hornets.

Bulls 92, Cavaliers 81

At Chicago, Kirk Hinrich outplayed his more-heralded rookie counterpart, LeBron James.

Two days after becoming the first rookie with a triple-double this season, Hinrich came close to a second with 22 points, eight rebounds and seven assists. When Hinrich left with less than a minute to play, Bulls fans gave him a standing ovation.

James had 18 points, but he shot just 7-of-17 with three rebounds and three assists.
