Will Clyburn and Chris Babb each scored 17 points and Iowa State trounced Texas Tech 86-66 on Saturday for its third straight win.
Melvin Ejim had 13 points and 13 rebounds for the Cyclones (19-8, 9-5 Big 12), who tuned up for Monday's home game with Kansas by outscoring the Red Raiders 50-37 in the second half.
The Cyclones stretched their lead to double digits, 50-39, with 13:52 to go and led by at least 10 the rest of the way. Iowa State went ahead by as many as 28 points in cruising to its 22nd straight home win.
Josh Gray had a game-high 20 points for Texas Tech (9-16, 2-12), which has lost eight in a row. Texas Tech handed Iowa State its only bad loss so far, stunning the Cyclones 56-51 in Lubbock last month. The Red Raiders haven't won since.
