Once and Again World Champion Fisher defends her Nationals title this weekend.

The Women's Professional Billiard Association's National Championship is underway at the Soaring Eagle Casino in Mt. Pleasant, Mich.

With a field of 64 - up from the usual 48 for Classic Tour events - the path to the final will be a little longer than usual, but it's likely that the ESPN-taped matches on Sunday will feature familiar faces. Top-ranked Karen Corr has swept the Classic Tour season with five championships; while Allison Fisher, who has won the last three "Nationals" is coming off big wins in Asia, including the World Pool-Billiard Association's World 9-Ball title. Also figuring into the mix is Jeanette Lee, who won the BCA 9-Ball title and the World Games gold medal this year.

Onsite coverage of the event will begin Saturday.
