It’s the final day of ACC women’s basketball before the tournament starts in Greensboro four days from now.

All three Triangle teams are, well, in the Triangle on a very big day for all involved.

It has been a long time since UNC has still been fighting for an NCAA berth in late February, but that’s the case for a Tar Heel team that has lost seven of its last eight games.

The Tar Heels will host No. 6 Duke today at 3 p.m. at Carmichael Arena in a game to be shown live nationally on the Fox Sports cable channels, and an upset of the Blue Devils on Senior Day might be just what Sylvia Hatchell’s club needs to nail down a bid.

That won’t be an easy task, as Duke routed the Tar Heels 79-51 on Feb. 8 at Cameron Indoor Stadium. In its third season under Joanne P. McCallie (pictured), the Blue Devils have already clinched an ACC regular season championship and want to keep making the case for a No. 1 seed going into the NCAA Tournament.

Today will be the final home game before the tournament for Tar Heel seniors Trinity Bursey and Martina Wood.

An hour before that one starts N.C. State, which has been one of the surprises of the ACC in its first season under Kellie Harper, will look for an upset over visiting No. 22 Georgia Tech in the Senior Day game for Nikitta Gartrell, Lucy Ellison, Sharnise Beal and Inga Muciniece.

State’s only home ACC loss this season has been to UNC.

There are six games on today’s ACC slate, and the only seeds already set for the tournament are Duke at No. 1 and Florida State at No. 2. Georgia Tech is also guaranteed a bye into the quarterfinals.
