PHOENIX, AZ (AP) -- Chane Behanan scored 15 points and Gorgui Dieng anchored Louisville's stifling defense with seven blocked shots, helping the Cardinals knock off top-seeded Michigan State 57-44 Thursday night in the West Regional semifinals.

Louisville (29-9) smothered the NCAA tournament's best-shooting team with its matchup zone, getting good pressure from its guards up top and some big swats by Dieng, one of the nation's top shot-blockers.

The Cardinals relied on 3-point shooting in the first half and went inside the second to befuddle the Spartans, earning a trip to the West final against Marquette or Florida on Saturday.

Michigan State (29-8) started slow and never got going against Louisville's amoebic defense, shooting 28 percent while being outscored 20-14 inside by the leaner Cardinals.
