Simon, Sage's top singles player, was sidelined with shoulder tendinitis. Longoria said he wants to take it easy with Simon to have him at full-strength later in the season.
Simon watched another top Lightning singles player, senior Andrew Kurzweil, come up big in the third round.
The match was tight throughout. Sage Hill had a 4-2 lead after a round but Newport Harbor tied it at 6-6 headed into the final round.
It was still tied at 8-8 – and also tied 68-68 in games – with two matches on the court. Kurzweil was playing Newport Harbor No. 1 singles player Jason Cernius, and the Sage doubles team of Nasier Emtaiz and Ryan Lee was playing Newport Harbor's Jamie Davis and Malcolm Faigen.
Kurzweil pulled out his set, 7-5, which clinched the match for the Lightning as the other set went to a tiebreaker. Davis and Faigen prevailed, 7-2, in the tiebreaker, but Sage Hill had the one-game victory.
The Lightning also had topped Newport Harbor in their Lightning Invitational two weeks ago.
"That was a college format and we had our No. 1, Robbe [Simon], then," Kurzweil said. "I feel like this is a much bigger win, emotionally. [Cernius] is a really good player so I went to Advantage Tennis Academy before this [match] and worked out there. I think it really helped me out."
Kurzweil swept his three singles sets and Denis Cirit also won two of three sets for the Lightning. Garrett Rapport, playing at No. 1 singles for Sage, lost his three sets but got games in each one, which turned out to be important.
