Clarke, the reigning Atlantic 10 Conference player of the week, was 6 of 8 from the field, including 5 of 6 on 3-pointers. Marshall made seven of his 12 shots as the Bulldogs (4-2) shot 59 percent from the floor.
The Bulldogs opened the game on a 15-2 run, capped by a Clarke 3-pointer, and were never seriously threatened. Butler was 9 of 18 on 3-pointers and dominated the glass, outrebounding Hanover 42-22.
Butler improved to 13-2 against Hanover, which has not beaten the Bulldogs since the 1909-10 season.
