CHICAGO, March 9 (Ticker) -- This time, the San Antonio Spurs blew through the Windy City without a problem.

Tim Duncan and David Robinson had their way up front as the Spurs extended their winning streak to five games with a 100-73 rout of the lowly Chicago Bulls.

In February 2001, the Spurs suffered one of their most embarrassing losses of the season here when they were beaten by the NBA's worst team, 105-104.

Duncan and Robinson made sure San Antonio avoided another humiliating defeat. Duncan collected 22 points and 11 rebounds en route to his league-leading 50th double-double of the season.

Robinson had 13 points and 11 board sas the Spurs never trailed and led by as many as 36 points in the fourth quarter.

Eddie Robinson scored 12 points to lead the Bulls, who suffered their fifth straight loss.

"I wasn't really pleased with tonight," Chicago coach Bill Cartwright said. "The effort was fine, but the execution was poor -- just not smart. Our offensive decision-making was not smart either."

The night started badly for the Bulls when forward Marcus Fizer suffered a sprained right ankle during pregame warmups. He did not play and is listed as day-to-day.

"I knew that it was going to be tough when I was driving up I-65," said Bulls forward Jalen Rose, who scored 11 points. "We have to find a way to keep plugging away to get better. Tonight we failed to compete."

Having his way down low from the start, Duncan scored eight points in the first 7 1/2 minutes as the Spurs raced to a 22-8 lead. Chicago went scoreless for more than five minutes to fall behind.

"I thought we had great focus tonight," Duncan said. "We started early and kept it on them. We took what we could get and the inside stuff happened to be there."

San Antonio methodically increased the lead, pushing it to 53-29 with 2:50 left before intermission on a layup by Steve Smith, who finished with 10 points.

"We started out really well," Spurs coach Gregg Popovich said. "This kept this young team from getting confidence. Tonight, our experienced guys took charge."

Duncan had 14 points and Robinson 10 in the first half, helping the Spurs to a 55-35 advantage at the break. They shot 54 percent (20-of-37) in the opening 24 minutes.

The Bulls were unable to rally in the second half, trailing by at least 17 points the rest of the way.

A jumper by Antonio Daniels with 6:16 remaining in the contest gave the Spurs their biggest lead at 96-60.

Malik Rose added 15 points for the Spurs, who shot 46 percent (37-of-80) and held a 48-34 edge on the boards. Chicago shot 40 percent (28-of-70) and committed 15 turnovers.
