While conference tournament action continues this weekend, champions will also be crowned in the three women's conferences that don't hold postseason tournaments. There's a three-way tie in the Ivy League. UCLA has the edge in the Pac-10, and the WCC features a winner-take-all finale between San Diego and Portland.

IVY. The most heated race features a three-way tie for first place going into the weekend. Columbia, Harvard and Princeton (all 4-1-1) sit atop the standings with 13 points apiece and one match remaining.

Columbia  and Harvard get the final day of the season started early, as they square off in Cambridge at 11 a.m. Later in the day at 4 p.m., Princeton hosts defending champion Penn.

Harvard is in the best shape to take the league's automatic bid to the NCAA Tournament: It wins the tiebreaker if it beats Columbia. Princeton wins the title if beats Penn and Harvard doesn't beat Columbia. Columbia needs to beat Harvard and hope Princeton doesn't defeat Penn.

PAC-10. UCLA can clinch the Pac-10 title with a victory at Oregon State on Friday. The Bruins (7-0-0) lead Stanford (7-1-0) going into the weekend and have the edge in head-to-head play, having won their matchup, 1-0, last Friday. UCLA moves on to face Oregon on Sunday. Stanford travels to Cal on Saturday.

WCC. San Diego will be vying for its first conference championship in its history when it hosts Portland Saturday at Torero Stadium. Both teams are 6-0-0 in conference play. The Pilots have won 15 games in a row, while USD takes a seven-game winning streak into Saturday's game.
