Of all the teams to end the San Antonio Spurs' 11-game winning streak. The Pistons proved up to the task Friday night with a 119-109 victory at the Palace. The Spurs can be excused because two key players weren't in the lineup. With an NBA-best record of 39-12, San Antonio was without Tim Duncan (sore left knee) and Manu Ginobili (left hamstring). Meanwhile, the Pistons learned Friday that rookie center Andre Drummond would be out for the next four to six weeks with a fracture in his fifth lumbar vertebra. "Injuries are part of the game," said coach Lawrence Frank after his team shot 51.7% from the field and had three players scored in the 20s. "We feel bad for Andre, but he'll be all right, and other guys have to step up. "I thought at the beginning of the game we had a great rhythm and flow. We had quality shots and great ball movement." The Spurs had been without Duncan and Ginobili for most of their streak, but the Pistons were hot from the field and never took the foot off the pedal. Greg Monroe, free from Duncan, had 26 points and 16 rebounds. Brandon Knight scored 24 points, and Charlie Villanueva had one of his best games as a Piston with a season-high 21 points, eight rebounds and five three-pointers.
