UPDATE 1: Ohio State has defeated Northwestern in the opener of their series, ending a long Wildcats' home winning streak. With Northwestern now having five conference losses, it will be a very tall order for it to catch Ohio State and Michigan, each of whom has only two losses in the Big 10.
UPDATE 2: Michigan has edged Iowa.
UPDATE 3: Stanford squeaked by Arizona, leaving each team with five losses in the Pac 10 (no team has fewer). UCLA, a winner today over Oregon State, is tied with Stanford and Arizona in the loss column.
