Entering the sixth weekend of Big Ten play, three of the Big Ten's top four teams will look to stay at the top of the standings with conference matchups on Saturday. Iowa, standing in first place with a 4-0 conference mark, will host Indiana while looking to improve to 9-0 overall for the first time in school history. Four-time defending conference champion Ohio State is just one-half game back in the standings at 4-1 and wraps up non-conference play at home against New Mexico State. Penn State, which shared last year's Big Ten title with the Buckeyes, is one game back in the standings at 3-1 and will face a road test at Northwestern. Michigan State stands in fourth place at 3-2 and plays at Minnesota on Saturday night. In other games, a pair of 2-2 conference squads will meet in Madison when Wisconsin hosts Purdue, while Illinois hosts Michigan.
