Rapid Reaction: Michigan St. 74, Purdue 56

Unsinkable Michigan State undoubtedly punched its Big Dance ticket with an upset romp over second-seeded Purdue, 74-56.

The season-long underachievers once again appear to be peaking at the right time, leading from the start. The Boilermakers were never really in the game in the second half. As much as the victory helps the Spartans' NCAA tourney résumé, this loss combined with the regular-season ending upset loss to Iowa hurts Purdue's seeding.

Star player: Michigan State guard Kalin Lucas shook off a rolled ankle from Thursday to light up the Boilermakers, scoring 30 points. Lucas was 4-for-4 from 3-point range in the first half and did his damage in the second at the free-throw line, making 10 of 11 foul shots.

Turning point: The Spartans jumped to a 10-2 lead and forced a Purdue timeout just 3:11 into the game. That set the tone for the rest of the night.

Key stat: Michigan State was 7-of-9 from 3-point range in the first half while the Boilermakers were 1-for-10.

What's next: The Spartans will face the winner of the Wisconsin-Penn State game in the Big Ten semifinals Saturday afternoon. Purdue will go home and try to regroup from a rough finish to the season.
