Maryland's 67-65 road victory over then-No. 1 Virginia last week vaulted the Terrapins (14-1) into the top spot in today's Associated Press women's college basketball poll.
The Terrapins, who also beat North Carolina 72-68 at home last week, received 65 first-place votes and 1,790 points from a nationwide panel of 72 coaches. Virginia (14-1) fell to second with six first-place votes and 1,703 points.
Stanford (12-1), which moved up a spot to third, received the remaining first-place vote and 1,642 points.
It's the first-ever No. 1 ranking in the 16-year history of the poll for the Terrapins, who became the 14th team to reach the top spot. Tennessee was No. 1 at the start of the season and was replaced by Virginia when the Vols were upset at Stanford.
Maryland was ranked 15th in the preseason and its steep move to No. 1 is exceeded only by Penn State, which started 18th last season and reached the top spot in January.
"The exciting part of the ranking is the attention I hope it will draw to our program and to women's basketball in our area," Maryland coach Chris Weller said.
"As to what this means in terms of our team, it's only January and we can't get too caught up in the ranking. We are going to have to play each game one at a time."
Tennessee (10-2), which could have contended for a return to the top spot, fell from second to fourth after an 80-78 overtime loss at Mississippi. Iowa (12-1), George Washington and Stephen F. Austin (12-1) retained the fifth, sixth and seventh positions, but Austin moved within three points of the Colonials.
Mississippi's victory over Tennessee enabled the Rebels (15-1) to jump two spots to No. 8.
