Kentucky finally got another test in the Southeastern Conference and the Wildcats' stingy, sticky defense helped them pass yet again and take a big step toward the regular-season conference title. Doron Lamb hit a 3-pointer with 3:18 left to put No. 1 Kentucky ahead to stay, and the Wildcats beat Vanderbilt 69-63 Saturday night for their 17th straight win by not allowing a point inside the final 4 minutes.
