DURHAM, N.C. (AP) Grayson Allen had 25 points and 10 rebounds, freshman Frank Jackson added 21 points and No. 1 Duke beat Grand Canyon 96-61 on Saturday.

Amile Jefferson scored 15 points, Luke Kennard finished with 14 and Matt Jones had 11 points for the short-handed Blue Devils (2-0).

Once again playing without three injured freshman post players, they kept things largely in their guards' hands and shot 53 percent to win their second game in less than 24 hours.

Now, with those two tune-up games out of the way, the focus squarely falls on one of the marquee matchups of the early season: a date with No. 3 Kansas on Tuesday night at Madison Square Garden.

Shaq Carr had 18 points to lead pesky Grand Canyon (0-1), which gave Duke more of a test than Marist did in a 94-49 rout a night earlier but came up empty in its second opener against a top-ranked team in three years.
