The win was significant because it broke a three-game losing streak, kept Michigan State in first place in the conference and gave them their 20th win of the season.
Lucas' effort offset a heroic 30-point effort by Penn State's Talor Battle. Battle canned 7-of-11 from three-point range in keeping the Nittany Lions close to the Spartans all afternoon until Michigan pulled away with a late second half run to put the game away.
Summers hit a three pointer, made two free throws and then watched as Roe made a tip-in, a slam dunk and a layup to give MSU a commanding 57-46 lead.
By the time the Nittany Lions responded, it was too late. The Spartans made the eleven point advantage stand up by trading baskets and free throws the rest of the way.
The Spartans now hold a half game lead over #6 Purdue, #16 Ohio State and unranked Illinois. The hold a full game lead over #13 Wisconsin. The Green-and-White travel to Indiana to face the 9-15 Hoosiers and Purdue before coming home to host last-place Penn State and the season finale vs. Michigan.
