PORTLAND, Ore. (AP) - Michael Finley's shot at the buzzer for San Antonio rimmed out and the Portland Trail Blazers edged the Spurs 100-99 Friday night.

With the score tied at 93, Brandon Roy hit a pull-up jumper for the Blazers, but San Antonio's Roger Mason answered with a 22-footer to tie it again.

After Rudy Fernandez missed one of two free throws, Tony Parker's reverse layup with 1:29 left gave the Spurs their first lead of the second half at 97-96.

Roy made a pair of foul shots to put the Blazers in front before LaMarcus Aldridge hit a shot from the top of the key to make it 100-97 with 35 seconds left.

After Parker hit a pair of free throws, Travis Outlaw's bank shot for the Blazers missed. Mason took the ball to the other end and appeared to have a clear path to the basket — but he passed off to Finley, who missed at the buzzer sounded.
