ANN ARBOR, Mich. (AP) — The Big Ten confirmed Tuesday that its regular-season basketball championship will be determined based on winning percentage.

Michigan, at 13-1 in conference play, is the current leader on the men’s side. Second-place Illinois, which is 14-4, played at Michigan on Tuesday night.

The clarification from a league spokesman was needed because Michigan is on track to play just 17 conference games, while Illinois is set to play the full 20. Assuming no more changes to the schedule, Michigan can wrap up the league’s top winning percentage by winning one of its final three games.

The race was closer on the women’s side. Maryland is 15-1 and Indiana is 14-2.
