(WEST LAFAYETTE) - Purdue held No. 8 Michigan State to its two lowest scoring halves of the season and lowest point total in nearly eight years as it snapped a two-game losing streak with a 71-42 upset. The Spartans (13-4, 5-1 Big Ten) came into the game as a 4 1/2-point favorite, averaging 81.3 points per game and a reputation for physical play. But Purdue bottled up Michigan State at every turn and eventually the Spartans buckled. Cassius Winston, the preseason pick for player of the year, finished with 10 points, five assists and nine turnovers. His teammates weren't any better. Rocket Watts had 10 points and Xavier Tillman finished with eight points and eight rebounds. Michigan State finished with season-lows in field goals (18), 3-pointers (two), field goal percentage (35.3) and 3-point percentage (12.5) while accumulating a season-high 18 turnovers. The 32 rebounds matched the Spartans' second-lowest total of the season, and the 42 points were their fewest since a 42-41 loss at Illinois on Jan. 31, 2012. The Boilermakers (10-7, 4-3), meanwhile, extended their home winning streak against conference foes to 15 and now have two victories over top-10 teams this season. Trevion Williams finished with 16 points, 7 rebounds and 4 assists for Purdue and helped fuel a big run, 13-2, that made it 34-14 with 3:23 left in the first half. Evan Boudreaux had 11 points and five rebounds while Sasha Stefanovic and Eric Hunter Jr. each finished with 10 points.
