Los Angeles  - Leave it to the seasoned veterans to end the San Antonio Spurs' regular-season on a high note. Michael Finley's buzzer-beating three-pointer sent the game into overtime and Tim Duncan had six of his 20 points in the extra session, to go with 19 rebounds, as the Spurs won the Southwest Division with a 105-98 victory over the New Orleans Hornets on Wednesday night.

The dramatic come-from-behind win, coupled with Houston's 95-84 loss to Dallas, clinched the third seed and home court advantage for the Spurs, who will meet the Mavericks in the first round of Western Conference best-of-seven game playoff series tips off this weekend.

"It's great that we have home court," Duncan said. "It's a great way to end the season."

The Spurs erased a five-point deficit in the final 49 seconds when Finley took a pass from Roger Mason and fired in his game-tying three just before the clock expired, sending the home crowd in a frenzy.

"Just enough time," Finley said. "Everything lined up for us."

With Finley providing the Spurs with a second life, Duncan dominated the extra five-minute frame with the half a dozen points, six rebounds and a pair of assists on the final day of action in the regular season.

"That was the old Timmy, just controlling the game," said Frenchman Tony Parker, who led the Spurs with 29 points.

David West scored 34, and Chris Paul had 26 with 14 assists for the seventh-seeded Hornets, who open their Western Conference playoff series on the road against second-seeded Denver this weekend.

"We played pretty good for about 47 minutes and 40 seconds, something like that," Paul said. "We got burned again with that last-second shot. We played him (Finley) as tight as possible, and he hit another tough shot as usual."
