OMAHA, Neb. (AP) — Caleb Grill scored a season-high 16 points, Izaiah Brockington had all 12 of his points in the second half and No. 19 Iowa State stayed unbeaten with a grinding 64-58 victory over Creighton. The Cyclones are 8-0 under first-year coach T.J. Otzelberger and an overhauled roster after going 2-22 last season. Ryan Hawkins scored a season-high 25 points to lead Creighton and Ryan Nembhard had 10. But the Bluejays (7-2) lost for the first time in 24 nonconference home games after committing 21 turnovers.
