The ranks of the unbeaten were thinned out even more Tuesday night.

Louisville, Maryland and Butler all lost for the first time, falling to Texas Tech, Penn State and Baylor, respectively. That left just five undefeated teams in all of Division I. There are also four teams that haven't won a game yet.

Here's a look at each of the remaining teams that are either unbeaten or winless.

First, the undefeated five:

OHIO STATE

Record: 9-0

AP Rank: 3

Pomeroy Rank: 1
