Chicago Michigan State might have cost itself a No. 1 seed.
Joe Crispin made an off-balance three-pointer with 21 seconds left, then sealed Penn State's victory with a pair of free throws as the Nittany Lions upended the Spartans 65-63 in the quarterfinals of the Big Ten tournament Friday night.
"Do I think we're deserving of a No. 1 seed? I don't know who else is going to lose. I would say probably not," Michigan State coach Tom Izzo said. "Do I think we're deserving of a No. 2 seed? Yes, and maybe a No. 1 if the right teams lose."
It was an ugly effort from the second-ranked Spartans (24-4), who had won a share of their fourth consecutive regular-season title and were looking for their third straight tournament crown.
Penn State scored 21 points off 17 Spartan turnovers. Michigan State also was hampered by 16-for-30 shooting from the free-throw line.
The Spartans are the highest-ranked team Penn State (19-10) has ever beaten. The victory might have sealed an NCAA bid for the seventh-seeded Nittany Lions, who were on the bubble after losing three of their last four regular-season games. Crispin finished with 22 points.
