GRAND RAPIDS, Mich. -- Tayshaun Prince sees no need to worry about the DET' offense.

Desmon Farmer scored 13 points while Tim Duncan had 10 points and eight rebounds to lead the SAS to an 86-64 preseason victory over the DET on Tuesday night.

The DET shot just 27.8 percent (22-of-79) from the field. It was the first win of the preseason for the SAS (1-2) and the first loss for the DET (4-1).

It was the lowest scoring total of the preseason for the DET, who eclipsed the century mark in their last game, a 111-99 victory over Milwaukee on Saturday.

"We didn't run our offense very well tonight," Prince said. "San Antonio did a good job in the first quarter taking us out of our stuff and getting an early lead. Give them credit."

The DET, who never led, closed to 48-44 early in the quarter on Richard Hamilton's 3-pointer, but San Antonio held Detroit scoreless for nearly seven minutes during a 12-0 run to regain control.

Ime Udoka's 3-pointer late in the third gave the SAS a commanding 69-46 lead.

"Sometimes, we'll get down and try to get it back too fast," Prince said. "Then we dig ourselves into a deeper hole. That's something we're going to have to work on.

"We win games off of our defense. That's something that San Antonio does. That's something we like to do and we'll get back to it."

Detroit's offense generated only two free throws in the final 9:44 of the third quarter and was 17-for-57 from the floor going into the fourth.

"Just look at the guys we have, we definitely have a good shooting team," said Detroit's Rasheed Wallace, who missed all seven of his field goal attempts. "We just couldn't knock them down tonight, not the ones we wanted."

Farmer saw the most court time of any player with more than 29 minutes. The USC product spent last season in the NBA Development League.

"I go out there and do what the coaches want me to do," Farmer said. "The players have helped me get through each game. I take it all in and try to put it on the court."

Farmer is confident he can make the SAS' roster.

"I'm not worried about it," he said. "I'm just trying to perform. Whatever happens happens."

San Antonio opened the game with an 11-0 run and led 26-18 after the first quarter and took a 48-38 lead at the half.

"You want to get some practice in and come out of this healthy," Duncan said of preseason games.

Will Bynum led the DET with 10 points and Jason Maxiell had eight rebounds.

"When your team doesn't do well you try to figure out what you can do as a coach and as a staff to make the team better," said DET coach Michael Curry. "We'll do that and get back to work and do some real productive things and come back for a much better effort."

Duncan laughed when asked if these two teams could meet again in the NBA finals.

"You never know, especially not now," he said.
