After 16 years coaching Tim Duncan, the Spurs' Gregg Popovich jokes that he's run out of things to say to his Hall of Fame-bound big man.

"We don't even talk to each other, we don't even look at each other," Popovich said. "I'm just happy he shows up for the games."

A missed bus or a busted alarm clock is about all that can stop Duncan during what has so far been an age-36 season for the ages.

On the second day of 2013, Duncan turned in a box score that would have made more sense on the second day of 2003, racking up 28 points, 13 rebounds and three blocks Wednesday to lift the Spurs to a 117-110 win over Milwaukee at the Bradley Center.

The victory was the Spurs' seventh in a row, boosting their record to 26-8. It extended what is now the longest in the NBA after the Los Angeles Clippers' string of 17 straight ended Monday in Denver.

"They're a tough team," said Milwaukee guard Brandon Jennings, who finished with 31 points, the second-most scored against the Spurs in regulation this season. "Once they go on their runs, they tend to bury you."

Duncan's final line was notable if only for how routine nights like it have become.

In the previous 15 days, Duncan had also produced a 31-point, 18-rebound night in a loss at Denver and had a 30-point night in a win over Houston.

Earlier this season, he posted a 22-point, 20-rebound night in a defeat at Utah and 22-point, 17-rebound opus in a win at Indiana.

Safe to say Duncan is so far winning his one-on-one battle with Father Time in a rout.

"He's been playing like that all season," point guard Tony Parker said. "We kind of, like, expect it now."

Duncan opened his 1,144th regular-season game Tuesday with a flurry of jumpers. By halftime, he had 20 points.

He had also grabbed seven rebounds, pushing past Bob Pettit for 16th on the NBA's all-time chart.
