The U.S. women’s youth movement is picking up speed.

Teenager Olivia Moultrie joined Jaedyn Shaw and Alyssa Thompson, her teammates on last year’s Under-20 World Cup squad, on the roster for the USWNT’s training camp ahead of its two games against Colombia later this month. While Thompson played at the World Cup in Australia and New Zealand, this is the first call-up for Moultrie and second for Shaw.

All three are 18 years old.

“This is about exposure for these players. Teaching, learning and obviously competing, whether it’s in training or in games,” interim coach Twila Kilgore said after the 27-player roster was released Wednesday. “It’s about a long-term process. It’s not about the immediate, it’s about the future.”

Two-plus months after its disappointing showing at the World Cup, the USWNT remains a team in transition. The search continues for a new head coach after Vlatko Andonovski stepped down following the round-of-16 loss in Australia and New Zealand, the U.S. women’s earliest exit ever at a major international tournament.

But with the Paris Olympics just nine months away, the USWNT has no time to waste. The retirements of veterans Megan Rapinoe and Julie Ertz leave the U.S. women with fewer than 10 active players from the squad that won a second consecutive World Cup in 2019.

(Abby Dahlkemper, Mallory Pugh, Sam Mewis and Tierna Davidson have been out with injuries.)

Players like Moultrie, Shaw and Thompson are the future of the USWNT, and the sooner they’re acclimated to the team and its environment, the better. For everyone.

“It’s really important that we create a pathway for them to integrate into the environment and learn from it so they can take advantage of their time when they’re in the environment but also when they’re in their home markets,” Kilgore said.

“Every time we expose younger players to this very unique and special circumstance, meaning this team but also high-quality international soccer, they learn something that affects their game,” she added. “The idea is basically we accelerate their development.”

Moultrie might be best known for bringing the lawsuit that forced the NWSL to abolish its rule prohibiting players under 18. But since signing with the Portland Thorns at 15, she’s established herself as a rising star.

She helped the Thorns win the NWSL title last season. This year, she started 11 of the last 13 games for Portland, which earned the No. 2 seed in the NWSL playoffs. She has two goals and three assists in 21 games this season.

“She’s a long-term player for U.S. Soccer,” Kilgore said. “She’s got a pretty good head on her shoulders in terms of understanding patience, not just on the field but in the process.”

Shaw has six goals this season, most by a teenager in NWSL history, and three assists for the San Diego Wave, which won the NWSL Shield with the best regular-season record.

“Jaedyn’s special quality is the final pass. There’s very few people that can play a final ball the way that she does,” Kilgore said.

There’s another benefit to having players like Moultrie, Shaw and Thompson in camp. These three, along with Sophia Smith, Naomi Girma and Trinity Rodman, will be the cornerstones of the USWNT for the next decade. Maybe longer.

Already having intel on them will give whomever is the new coach a head start.

“It also gives the new coach an opportunity to have some information about how they adjust to the environment and, if they do play, what their first look is actually like and where they are in the process,” Kilgore said.

Shaw did not play in last month’s games against South Africa, and it won’t be a surprise if neither she nor Moultrie get time against Colombia. Las Cafeteras reached the World Cup quarterfinals, and they have one of the game’s most exciting young players in Linda Caicedo, and Kilgore is more likely to go with an established lineup. Especially with Becky Sauerbrunn and Smith back from injuries.  

The games are Oct. 26 in Sandy, Utah, and Oct. 29 in San Diego.

Still, getting these young, talented players in camp now is sure to benefit the USWNT next summer. And beyond.
