"I didn't know that, but it's a great accomplishment," Duren said. "A lot of it comes from having great teammates and playing on successful teams."
Duren also dished out six assists and made four three-pointers.
Senior guard Tyrone Garland added 17 points, and junior center Steve Zack finished with 13 points and 11 rebounds for his conference-best eighth double-double of the season.
"They have such a good all-around team," Duquesne coach Jim Ferry said. "They are going to contend for the conference title. They are as good as anyone."
Duren had 10 points and Garland added nine as La Salle outscored the Dukes, 22-12, over the first 101/2 minutes of the second half to extend a 35-30 halftime lead to 57-42. There were eight lead changes in the first half until Zack's jumper with 2 minutes, 12 seconds remaining put the Explorers ahead for good, 29-28.
Junior forward Dominique McKoy, who was recruited heavily by La Salle as a high school player in Atlanta, had 15 points and 11 rebounds for Duquesne (8-6, 1-1). The Dukes' five-game winning streak ended.
"It's great to start off 2-0, because this conference is so difficult," La Salle coach John Giannini said. "The difference between finishing 9-7 and 8-8 could mean the difference between finishing in ninth place or fifth. Every win is a big win, especially on the road."
