The Timberwolves have an opportunity to move three games in front of San Antonio atop the Midwest Division.
Without Troy Hudson (sore right ankle), Garnett spelled Cassell at point guard and became just the 17th player in NBA history to reach 13,000 points, 7,000 rebounds and 3,000 assists.
“I didn’t ask for this assignment,” Garnett said. “It was kind of shoved in my mouth, but it’s something I can swallow. We just simplify the game a little bit.”
Garnett running the point wasn’t the only lineup change for the Wolves. Center Michael Olowokandi, who started the past 12 games but struggled to adjust to the offense, came off the bench and chipped in 10 points.
“Playing with our secondary unit gives me a situation I’m more familiar with,” Olowokandi said.
Szczerbiak had his second straight strong performance in extended minutes as he works his way back from a heel injury. Szczerbiak had 24 points in 30 minutes Friday and played 23 more Sunday.
After missing nine games with a left knee injury, Duncan came off the bench for the first time in his NBA career in the Spurs’ 106-86 victory over the Timberwolves on Thursday. He had 22 points on 6-for-15 shooting and 10 rebounds in that game.
San Antonio has won two straight following a two-game skid.
“We seem to have problems with the teams we’re supposed to do better against,” said Duncan, whose team has lost to Golden State and Cleveland in recent weeks.
Ginobili, who is averaging just under 18 points in his last five games. Ginobili shot 7-for-10 from the floor and made all nine of his free throws.
