The Timberwolves went inside to Pekovic early, who rewarded the team with a pair of short jumpers over Duncan. He finished with 14 points and three rebounds in the first half, but was limited to eight points and three rebounds in the second half while battling Duncan, Ayres and Baynes for positioning.
"Pek's huge, he's a strong boy," Duncan said. "He killed us on the offensive glass, especially in the first half. He had a great game tonight all around."
With the defense limiting Minnesota, San Antonio turned to its ball-sharing offense to seal the victory. The Spurs had 31 assists on their 42 field goals while shooting 57 percent from the field.
"That's just Spurs basketball," Love said. "They're very unselfish, they make the extra play and that's tough to beat, especially when they have a couple of Hall of Famers in there. They've played together for a long time and they're a good team. We played them well through the half and then they became the San Antonio Spurs."
After passing the ball off twice to reset from long range, Bonner drained a 3-pointer that gave San Antonio a 22-15 lead.
The Spurs will need more of that when they travel to New Orleans to face the Pelicans on Monday night without Green, Splitter and, possibly, Ginobili.
"(Green) will be out," Popovich said. "He won't go on the trip so we've lost him."
NOTES: Ginobili missed his second straight game with tightness in his left hamstring despite a four-game break between games. ... Green did not return after spraining his left index finger early in the second quarter. Making his second consecutive start after coming off the bench in 11 straight, Green missed his only field-goal attempt and had three rebounds in 9 minutes before getting hurt. ... The Timberwolves have alternated wins and losses in their past eight games. They next play at home Wednesday against Sacramento. ... Splitter (sprained right shoulder) missed his third straight game. He is expected to miss another two to four weeks with the injury, which occurred early in the fourth quarter of San Antonio's home victory over the Los Angeles Clippers on Jan. 4.
