TODAY’S GAMES / AT CHICAGO

* Stanford (27-4) vs. Western Michigan (21-7): Stanford, seeded third in the region, is favored over No. 11-seeded Western Michigan, but the Broncos are crowd favorites after their upset of Clemson, partly because their Kalamazoo, Mich., campus is only a couple of hours from Chicago. Stanford had a little trouble with the College of Charleston in the first round, but has a tremendous height advantage over Western Michigan, which doesn’t have a player taller than 6 feet 7. The Broncos rely on guards Rashod Johnson--who had eight three-point baskets against Clemson--Saddi Washington and Jason Kimbrough.

* Purdue (27-7) vs. Detroit (25-5): Tenth-seeded Detroit is also trying to keep an upset run going after a mild surprise over St. John’s. Detroit is 1-13 in games against Purdue, but Coach Perry Watson said the team won’t be overwhelmed. “Our guys have played against some tremendous teams this year--Michigan, Michigan State, Cincinnati--so we’re not going to be intimidated,” Watson said. Guard Derrick Hayes scored 27 points against St. John’s. “I hope our bigness can neutralize their guards,” Purdue Coach Gene Keady said. “Hayes will be hard to contain.” Purdue beat Delaware by 39 in its first game, and got a boost from the return of Jaraan Cornell, who had been sidelined because of a sprained ankle.
