Pittsburgh powered its way to a familiar place.
Sam Young, the Panthers' poet in motion, scored 32 points and DeJuan Blair added another double-double as top-seeded Pittsburgh advanced to the round of 16 for the fifth time in eight years with an 84-76 win over Oklahoma State on Sunday.
Pitt (30-4) will play Xavier in the East Regional semifinals in Boston on Thursday.
Obi Muonelo scored 19 points for the eighth-seeded Cowboys (23-12), who gave the Panthers all they could handle before losing their touch in the final minutes. Oklahoma State made 10 3-pointers in the first half but made only two of 12 from long range after halftime.
