The Jamestown boys and girls tennis each advanced to the Group 4A team tournament, where each will compete on Monday.
The Jamestown boys overcame a strong Hanover team 5-1 to advance to the state semifinals.
Albon Yowell and Trey Montgomery battled through three sets to claim their wins and Philip Song, Paul Pieper and Alex Lambert brought home their victories in two sets.
Jamestown's No. 1 doubles team of Grayson Deberry and Yowell will enter states as a No. 1 seed after winning the 4A East Regional Championship 6-1, 6-0 at Dinwiddie High.
Song and Jordan Deberry took Midlothian to a third set before falling.
Yowell also advanced in individual singles after a 6-7 (7-9), 6-1, 6-3 victory over Midlothian's Venkat Chekati.
Jamestown's 20-game winning streak and its hopes of reaching the 4A state tournament ended with an epic 2-1, 13-inning loss at defending state champion Hanover.
In a game that didn't end until past 11 p.m., Danny Lopez hit a double to the fence to bring home Brian Sisson with the winning run, setting off celebration for the Hawks (21-2) and dejection for the Eagles (20-3).
Jamestown got outstanding pitching all night. Ryan Devine struck out eight in 8 2/3 innings, yielding four hits, five walks and an unearned run. Andrew Barrow took the loss despite striking out eight in four innings. He gave up three hits and a walk.
The Eagles went ahead in the third inning when Barrow tripled and came home on a Devine groundout. Sisson scored the tying run in the fifth on a throwing error.
Barrow and Kevin Mooney each had two of Jamestown's seven hits. The Hawks also had seven hits.
Warhill's Keely Rochard (23-0) pitched yet another shutout, a one-hitter with 15 strikeouts in this case, as the unbeaten Lions won 6-0 at Skyline to return to the state 3A semifinals.
First, Warhill played for the East region title Friday at York.
Lions freshman Taylor Nicholson belted a first-inning home run and scored three times in Thursday's win.
