Kobe Bryant scored 30 points and helped the Los Angeles Lakers score the last 20 points of the third quarter in a 92-77 victory over the Detroit Pistons on Thursday. The Western Conference-leading Lakers have won four straight games to pull within a victory of Cleveland's NBA-high total of 58, and five in a row on the road for a league-high 26. Detroit reserve Will Bynum had career highs with 25 points and 11 assists and helped the Pistons outscore the Lakers 30-14 in the second quarter to lead 42-39. The Pistons built a 10-point lead early in the second half and were ahead by five midway through the third quarter when Bryant made a layup and Trevor Ariza had consecutive putback dunks to spark a 20-0 run. The Lakers snapped a nine-game losing streak at The Palace, including three losses in the 2004 NBA Finals.
