MCLEAN, Va., Jan. 31 (UPI) -- Ohio State remains the unanimous No. 1 in the USA Today/ESPN men's coaches' basketball poll but Big 12 teams have moved into the next two spots.

Ohio State (22-0) is the only major college team without a loss this season and pulled in all 31 first-place votes for the second consecutive week. The Buckeyes survived a 58-57 scare at Northwestern and beat No. 10 Purdue earlier in a week that saw 17 of last week's Top 25 teams, including seven of the Top 10, suffer at least one loss.

Other than Ohio State, the Top 10 teams that escaped the series of upsets were Big 12 members Kansas (20-1) and Texas (18-3). The reward for that was the Jayhawks moving from sixth to No. 2 and the Longhorns jumping from eighth to third.

Pittsburgh (20-2) slips to No. 4 with Duke (19-2) in fifth, San Diego State (21-1) sixth and Connecticut (17-3) at the No. 7 spot. Those teams each fall two places this week.

Notre Dame (17-4) improved six places to eighth while Brigham Young (20-2) holds steady at ninth and Purdue (18-4), despite a loss, moves up two to 10th.

Kentucky (16-4) goes from 16th to 11th while Villanova (17-4) is down five to 12th. Louisville (17-4) and Georgetown (16-5) both go up six positions to Nos. 13 and 14, respectively. Missouri (17-4) takes up the No. 15 spot.

Texas A&M (17-3), basically trading places with Kentucky, comes in at 16th. Syracuse (18-4), on a four-game losing streak and No. 3 two weeks ago, is 17th with Wisconsin (15-5) at 18th, Washington (15-5) in 19th and Minnesota (16-5) 20th.

Utah State (20-2) improves four places to 21st with Arizona (18-4), the only new entry this week, in at 22nd. Florida (16-5) is No. 23 and Illinois (14-7) and Vanderbilt (15-5) are tied for 24th.

St. Mary's dropped out of this week's Top 25.
