The loss drops MSU to 17-4 on the season, 7-2 in the conference and brings several teams, most notably their nemesis Purdue, into striking distance as the Spartans were trying to claim their first Big Ten regular season conference championship in eight years (2000-01).
The Lions were powered by the three point shooting of Talor Battle who scored 29 points on 6-of-12 shooting from the three point line and 11-of 19 from the field.
Kalin Lucas scored 23 points to lead the Spartans, but suffered from a 7-for-21 day from the field and a 1-of-3 day from three point land. Chris Allen chipped in with eleven but continued his three point drought, going 1-of-5 from the arc.
The Nittany Lions extended their one point halftime lead to five before Lucas and Goran Suton combined on back-to-back hoops to briefly tie the game. But after a Suton turnover at the 14:23 mark, Penn State went on a 10-0 run behind two three pointers by Talor and two layups by Jamelle Cornley.
Penn State held the ten-point lead as late as 4:19 in the contest when MSU mounted a comeback behind four straight points by Allen and a Lucas free throw which cut the lead to five.
The Spartans cut the lead to one but missed an attempt to tie the game when Lucas made just one of two free throw attempts with :12 left and Suton fouled Penn State's Andrew Jones who made one of two from the line. Lucas missed a jumper with :05 left that would have sent the game into overtime.
Jones salted the contest away by making one one of two from the line.
Michigan State, who was certainly hurt by the loss of one of their top starters, small forward Raymar Morgan who continues to suffer from flu-like symptoms, now tries to regroup before hosting a dangerous #24 Minnesota squad (18-3, 6-3 Big Ten) on Wednesday, who lurks just 1 1/2 games behind the still first place Spartans.
