SAN FRANCISCO — Violet shirts adorned every seat inside Chase Center with the script “First of a Lifetime.” Before long, they were filled as the Golden State Valkyries tipped off against the L.A. Sparks, and the WNBA had officially come to the Bay Area.

“We’ve been talking about this day for awhile,” Valkyries coach Natalie Nakase said in her pregame press conference. “Had this day marked, circled, highlighted. We’re ready.”

The Valkyries were announced as the WNBA’s 13th franchise on Oct. 5, 2023 — the first expansion team in the league since the Atlanta Dream in 2008.

Season ticket sales have already exceeded 10,000, which makes the Valkyries the first to hit that milestone.

Fans were allowed in at 5:30, and Brie Reddick of San Bruno, sporting her own Valkyries T-shirt, was among the first to absorb the scene. She has been waiting for a Bay Area franchise since the Sacramento Monarchs of the WNBA folded following the 2009 season after playing two years.

“I was here at the first preseason game and it was emotional to see everything happening,” Reddick said. “It’s weird because it’s not that Warrior blue but it’s something that’s still ours. We’re able to take ownership of it as fans and it’s so exciting.”

Their first home exhibition game on May 6 drew 17,428 in an 83-82 loss to the Sparks. Anticipating the real thing Friday night, Reddick, a basketball player in middle school, looked around the arena and took in the magnitude of the moment.

“I didn’t think it would get to the level it is today and to have the impact on girls, with college basketball in general and now the WNBA, it’s not something we ever expected, but I’m glad to see it happen,” Reddick said.

Reddick’s aunt, Elisha Reddick, has always been a basketball fan “but I always wondered why (women) can’t have teams. That was back in the 70s.”

Jenny Quintal of San Francisco, seated with her daughters aged 13 and 10, is a season-ticket holder along with her husband and only recently got hooked on the women’s game.

“If it wasn’t for my daughters, I wouldn’t be here,” Quintal said.

Astrie Martinez, wearing a sequined purple Valkyries jacket, lives on the Peninsula and immediately put her name on the list for season tickets.

“I’m so glad this is happening now,” Martinez said. “I see so many little girls here and that’s the coolest thing.”

Richard Martinez of Daly City saw the exhibition games in which the Valkyries went 1-1 against the Phoenix Mercury and the Sparks and isn’t convinced the expansion status will relegate the new team to struggle out of the gate.

“I like the whole spirit that the women have,” Gonzalez said. “Hopefully, in the near future they can expand more. There are quality players here and they’ve got experienced players. I’m sure some of the players they cut they wanted to keep.”

Los Angeles coach Lynne Roberts starred at Enterprise High in Redding as well as Seattle Pacific before moving up the coaching ladder starting at Chico State. She was mentored by former Stanford coach Tara VanDerveer and as a Northern California native felt at home.

“I was raised on the 49ers and the Giants and the Warriors so it feels very comfortable to be back here,” Roberts said. “But what a day for women’s college basketball and this expansion team. We were here for a preseason game and the crowd was impressive. It’s a cool day for our sport and they seem to already have it kind of going here.”

Nakase could feel the intensity swelling in the Bay Area during the exhibition games and the run-up to the season.

“I mean, when we’re down by 14 they still have our backs,” Nakase said. “That’s the kind of fan base we want, someone that is going to support us when we’re down, and when we’re up, to start screaming again. They are definitely part of us.”

Nakase even got to shadow Warriors coach Steve Kerr for two days during the NBA playoffs to pick up a few pointers.

“He sat me down and before I could even ask a question had ideas and advice for a first-time head coach,” Nakase said. “What I learned from Steve was to always be yourself. His way of communicating to me, to his players, is second to none. Steve has so much experience and hopefully I’ll get just one percent of his knowledge.”

Nakase was too much in the moment to dwell on the historical significance.

“I think once I go through the full season, I think that will be history,” Nakase said.
