It was the sixth straight game the senior forward recorded a double-double and the 14th in the last 15. Dunston, 12th in the conference in scoring with a 15.4 average and tops in rebounding at 9.9 per game, was 10-for-17 from the field and blocked three shots.
Ruben Guillandeaux had 15 points for the Explorers, while Jerrell Williams added 14 and Kimmani Barrett had 10. Green made both of his 3-point attempts and La Salle finished 5-for-10 from beyond the arc and shot 56.3 percent overall (27-for-48).
