Indiana State studied how Cleveland State guarded John Jenkins back in November. Then coach Greg Lansing put Steve McWhorter on Vanderbilt's best player, as he usually does with any opponent. McWhorter held the Southeastern Conference's top scorer to a season-low 11 points and the sophomore guard hit two free throws with 3:32 left to put Indiana State ahead for good as the Sycamores upset No. 25 Vanderbilt 61-55 Saturday for their first win over a ranked team since 2006.
