The Big Ten basketball regular season is down to the final four games Sunday. Teams are still jockeying for Big Ten Tournament seedings with positions 2 through 4 earning the all-important triple-bye to the quarterfinals.

Michigan has wrapped up the top seed in next week’s expanded Big Ten Tournament, winning the regular-season title with a few games to spare.

Purdue, which began the season ranked No. 1 in the country, will be the No. 7 seed in the Big Ten Tournament after losing Saturday at home to Wisconsin, and UCLA beating USC.
