Louisville figured its game against Michigan State to be low-scoring, a natural expectation with two of the nation's best defenses butting heads. The Cardinals had one big advantage: Gorgui Dieng. Dominating inside, Dieng blocked seven shots and altered several others to anchor a stifling defense that helped Louisville knock off top-seeded Michigan State 57-44 last night in the West Regional semifinals. Louisville is in the regional final for the third time in six years, meaning a trip to New Orleans and the Final Four is within its sights. (More March Madness stories.)
