The University at Buffalo gained one place, from 20th to 19th, in the AP Men's Basketball poll announced Monday.
Ironically, the Bulls (13-1) moved up because the only team it lost to, Marquette, fell from 16th to 21st in the poll of 64 media members.
Coach Nate Oats' team also is ranked 20th in the USA Today Coaches Poll. The Bulls were tied for 20th in that poll last week.
UB will put its ranking on the line Tuesday night against a formidable Mid-American Conference opponent, Toledo, at 7 p.m. in Alumni Arena.
The Bulls defeated the Rockets, 76-66, in the championship game of the MAC postseason tournament in Cleveland. UB also defeated Toledo, 104-94, at home last January. UB will play the return game at Toledo on Feb. 16.
It was the ninth week in a row that UB was ranked in the AP Poll, most ever by a Mid-American Conference team in one season.
The Bulls won their only game last week, defeating Eastern Michigan, 74-58, in Ypsilanti in their conference opener.

In the Coaches Poll, St. John's and Iowa State cracked the top 25, Wisconsin and Nebraska dropped out.

Ball State ended Toledo's win streak at 10 games. The other Toledo loss was at Wright State on Nov. 14, 84-74.
The Rockets never got untracked against a Ball State team that is expected to be a challenger for the MAC title.
UB has to be wary of the Rockets, who are an experienced team with good size and shooting. they have four starters back from last year's MAC tournament runner-up team.
Senior guard Jaelan Sanford, who has started 114 career games, leads the Rockets in scoring at 17.8. He is a 3-point shooting threat and one of the best free-throw shooters in the MAC.
Other starters are 6-foot-8 senior forward Nate Navigato, 6-0 sophomore guard Marreon Jackson, 6-6 junior forward Willie Jackson and 6-11, center Luke Knapke. Sixth man Chris Darrington was the Rockets' leading scorer against Ball State with 13 points. He is a 6-1 guard who transferred from Tennessee. Freshman A.J. Edu, 6-10, provides frontcourt depth.
