Indiana's Victor Oladipo (4), Christian Watford (2) and Notre Dame's Jack Cooley (45) battle for the loose ball during the first half of an NCAA college basketball game, Saturday, Dec. 17, 2011, in Indianapolis.

INDIANAPOLIS — Cody Zeller scored 21 points and had eight rebounds to help No. 18 Indiana beat rival Notre Dame 69-58 on Saturday in the Crossroads Classic.

The Hoosiers are 10-0 for the first time since 1989-90 and protected their first Top 25 ranking in more than three years.

Eric Atkins led Notre Dame (7-5) with 15 points. But the only Division I team with six players who have scored 20 points in a game this season struggled badly against the Hoosiers' defense. Notre Dame shot 38.1 percent from the field and went more than 16 minutes without a basket during one stretch.

Indiana went on a 12-2 run during the drought to take its first lead of the game, then pulled away in the second half.
