Four districts were represented in the opening round of the PIAA state Class AAA singles tennis championships Friday at the Hershey Racquet Club.

On Saturday, only District 1 survives after an impressive performance in which Conestoga's Kevin Wang, Neshaminy's Alex Fioravante, Unionville's Michael Furr, and North Penn's Mike Buxbaum played out to the semifinals.

Wang, Fioravante, and Furr won opening-round and quarterfinal matches in straight sets.

Buxbaum took down his opening-round opponent in straight sets and reached the semifinals when District 10 champion Alex Brzozowski defaulted after dropping the opening set, 6-0.

At 11 a.m. Saturday, Wang will play Fioravante and Furr will face Buxbaum in the semifinals.

In doubles, half the semifinal draw consists of District 1 teams as the Wissahickon brothers of Andres and Ricardo Prince and Radnor's team of Gavin Studner and Andrew Zhong both won their first two matches Friday.

Studner and Zhong, the district champions, will face District 3's champions of Andrew and Alec Grossman (Cumberland Valley) in a marquee semifinal match at 11 a.m.

Class AA. The Harriton doubles team of Sam Borowsky and Max Blumenthal, both juniors, reached the semifinals with a pair of wins.

Borowsky and Blumenthal knocked off a pair of seniors from Hughesville, Cody Butler and Randy Davis, 6-4, 6-1, in the first round and also registered a straight-set win in the quarterfinals with a 6-1, 6-2 win over District 11 champions Andrew Ma and Madhav Valla of Moravian Academy.

In singles, District 1 champion Connor Pietrak of Holy Ghost Prep won his first-round matchup against District 4 runner-up Michael Clark of Lewisburg, 6-2, 6-4, but was eliminated by York Suburban's Evan Andrews, 6-4, 6-3, in the second round.
