Senior Micaela Vierra won her 10th game of the season, yielding four hits while striking out eight.
Huntington, which has won four in a row and eight of its last nine games, improved to 2-0 in league and 14-3 overall.
"It was important for us to get off to good start in our league which is the area's best," Huntington Coach Jeff Forsberg said. "The Fountain Valley game was an electric atmosphere as we had a great crowd and we played to that quite well.
"With spring break and two away games pending, we will have our work cut out for us but so far this group is really staying within the system and playing well."
Edison also only needed five innings to subdue Newport Harbor and routed the Sailors, 13-0. Liz Talataina hit a three-run home run and finished with four RBIs, Riley Wester went four for four with two RBIs and stole two bases, Ali Wester went three for three with an RBI and stole three bases, Kayla Neff doubled and singled and drove in a run, and McKenna Doose doubled, had a sacrifice fly and three RBIs.
Kiana Pancino (6-4) was perfect in five innings and finished with 11 strikeouts as Edison went to 2-0 in league and 6-5 overall.
"The girls are coming out to the field ready to play every day," Edison Coach Kim Ensey said. "We came out strong and Kiana (Pancino) pitched a great game."
Defending Sunset champ Marina squared its league mark at 1-1 by rallying from a three-run deficit to win, 5-4, in eight innings at Los Alamitos.
Keala Cordeiro started the top of the eighth with a single, moved to third and scored when freshman catcher Ryan King singled up the middle.
"We are getting back on track from our slump," said Marina Coach Shelly Luth whose team is ranked eighth this week in CIF Southern Section Division 1. "It was a huge win for us. Coming from behind and winning is a great way for us to rejuvenate ourselves.
