The No. 2 Tar Heels rolled over Tennessee 6-2 at Fetzer Field on Saturday, earning their way into an NCAA quarterfinal date with Texas A&M.

The teams will meet at 1 p.m. Saturday in Chapel Hill. The Aggies are the only team this season to beat the Heels -- a 1-0 double-overtime victory on Aug. 25 in UNC's season opener.

Carolina(24-1-0) is a vastly different team than it was in August. Its large freshman class has been seasoned by ACC play and some of its older players are performing at their peak.

And yet, UNC coach Anson Dorrance sees a team that hasn't yet reached its potential.

"There's still another level in us," he said. "We saw moments of that level last weekend, and I'd love for us to get back to there by the time we play Texas A&M on Saturday."

UNC beat UNC-Asheville 7-0 and Navy 4-0 in the first two rounds of the NCAA Tournament last weekend. Against Navy, Dorrance saw stretches where his team played with an overpowering speed.

Although the score was lopsided Saturday, Carolina wasn't quite as dominant as it would like to be at this point in the season. Still, there were moments when the Tar Heels played with enough speed to earn extra time with the ball.

In the 19th minute, Whitney Engen sent a throughball to Heather O'Reilly, who used her speed to gain a couple of extra steps on her defender. O'Reilly had time to make the perfect cross back to Engen, who buried it into the net for a 2-0 lead.

The Heels had scored their first goal minutes earlier when Tobin Heath collected a rebound off of a backsave and sent it to Ali Hawkins, who headed it in.

"It definitely helps," Heath said. "It's always good to get goals early, and it kind of let us settle down and relax."

Carolina added goals from Yael Averbuch (32nd minute), Elizabeth Guess (57th), O'Reilly (62nd) and 5-foot freshman Ashley Moore (77th).

Facing a 6-0 lead, the Vols put up two quick goals in the last five minutes of play. Dorrance admitted some relief that Tennessee (12-7-4) scored -- the Vols are coached by former Tar Heel Angela Kelly.

Still, the Heels are outscoring their opponents 17-2 thus far in the NCAA Tournament.

Although Carolina wouldn't admit to any desire for revenge against the Aggies, there's another subplot that could be some cause for concern this week.

O'Reilly is scheduled to leave Chapel Hill this morning to join the U.S. women's national team, which plays its first Women's World Cup qualifier on Wednesday.

The Americans play the winner of today's Mexico and Trinidad and Tobago match.

O'Reilly said she will return just in time for the Heels' annual Thanksgiving feast and will play Saturday. The senior has one goal and five assists so far in the NCAA Tournament.

"I thought last weekend was her best weekend of the year, and I thought today she played even better," Dorrance said. "So, I'm kind of excited. She's really starting to peak now, just moving with the ball with so much confidence."
