Kansas had a share of its ninth Big 12 regular-season title in a row even before Ben McLemore scored a layup off the opening tip at Baylor. That ended up being the only lead the fourth-ranked Jayhawks had, and as close as they came to claiming the outright league title on the final day of the regular season. Pierre Jackson had 28 points with 10 assists and Cory Jefferson scored 25 points, mixing in his first three career 3-pointers with his usual powerful dunks, and Baylor handed the Jayhawks their worst loss in seven years. The 81-58 loss Saturday night kept Kansas from winning conference regular-season title outright for the fifth year in a row.
