CHARLOTTESVILLE -- Now comes the difficult part for the University of Virginia's tennis team.

The top-ranked Cavaliers (30-0) completed the first phase of the NCAA Men's Division I Championships yesterday with a 4-0 rout of Penn State in the second round of the Charlottesville Regional.

The match started at the Snyder Tennis Center but finished on the indoor courts at the Boar's Head Sports Club because of rain. It didn't matter where the matches were played. U.Va., with probably the most talented and experienced lineup in coach Brian Boland's seven-year tenure, easily advanced to the round of 16, which starts Friday in Tulsa, Okla.

From now on, however, it won't be a cakewalk for the Cavaliers, who will take on Michigan next. Other potential matchups in later rounds could be No. 4 Mississippi, No. 2 Ohio State, No. 3 UCLA or No. 5 Georgia, which ousted U.Va. in the semifinals a year ago.

"I feel like we have the team to do it this year," said Treat Huey, who supplied one of the singles points at No. 2 with a 6-4, 6-4 victory over Adam Slagter.

"We have so much depth this year. We brought in two freshmen [Sanam Singh and Michael Shabaz] this year that are unbelieveable players."

In tying the school record for wins, the Cavaliers already have beaten nine of the other 15 seeds in the tournament.

"We have three veteran leaders on our team . . . and I think we have some of the best doubles teams in the country," said senior Somdev Devvarman, who won the NCAA singles title last season.

"Overall, we're a lot more solid team. We're a lot more mature."

Although Devvarman was on the verge of clinching the match at No. 1 singles, that honor went to another senior, Ted Angelinos, who defeated Guillaume St-Maurice 6-3, 6-3 at No. 6.

"This obviously feels a lot more special than the other ones, because we know every match we play from now on, it's win or go home," said Angelinos, whose parents are here from Athens, Greece, to watch him.

The other singles point was produced by Shabaz, who finished his 6-2, 6-1 romp over Eddie Bourchier at No. 5 before the rain came. Huey needed only a few minutes after the matches were moved indoors to wrap up his victory and Angelinos soon followed suit.

"We came in with a lot of energy," Boland said. "We played as good in doubles as we've played all year long, and I really felt that carried us throughout the day. The doubles was extremely impressive."

The Cavaliers will need to claim more doubles points and produce solid play in singles to win four matches and capture the NCAA tournament.

"I couldn't feel better about our team as we move into the final 16," Boland said.
