Trinity Armstrong Bio
Trinity Zion Armstrong (born July 25, 2007) is an American professional soccer player who plays as a center back for San Diego Wave FC of the National Women’s Soccer League (NWSL). She is widely regarded as one of the most promising young defenders in American soccer after a standout freshman season at the University of North Carolina and a rapid rise to the senior national team setup. Armstrong helped the United States win a bronze medal at the 2024 FIFA U-17 Women’s World Cup before turning professional with the Wave in 2025.
Standing 5 feet 6 inches tall and wearing the number 3 jersey, Armstrong has built a reputation for composed defending, aerial strength, and the ability to read the game beyond her years. She signed a three-year professional contract with San Diego Wave FC and quickly became a regular starter as a 17-year-old, earning a place on the NWSL Team of the Month in her debut season.
Early Life and Background
Trinity Zion Armstrong was born on July 25, 2007, in Frisco, Texas, a city located north of Dallas. She began playing soccer at the age of three, developing her skills in a region of Texas known for producing top-level talent. She is the daughter of Karla Nunn and has two older brothers. Her mother played college soccer for the University of Kentucky, providing Armstrong with an early connection to the sport at the household level.
Armstrong attended Hebron High School in Carrollton, Texas, for one year before transferring to IMG Academy in Bradenton, Florida, one of the most respected soccer development programs in the United States. During the summer before her planned junior year, she was hospitalized with anemia and at one point feared she might have to medically retire. She recovered, returned home, and played for FC Dallas in the ECNL, where she earned All-American honors and also trained with NWSL side Racing Louisville as a preseason invitee.
Facing the prospect of losing several future North Carolina teammates to the NWSL draft, Armstrong made the decision to reclassify and graduate early. That choice allowed her to enroll at the University of North Carolina at age 17, accelerating her path toward both collegiate and professional soccer.
Path to Soccer
Armstrong’s pathway into the highest levels of the women’s game ran through elite youth clubs, national team identification, and a single dominant college season. After her time with FC Dallas in the ECNL, she had already established herself as one of the top young center backs in the country. Her commitment to North Carolina came before her junior year of high school, and her subsequent reclassification moved her timeline up by a full year.
On the international stage, she was called into a United States under-15 camp in 2022 and won the Montaigu Tournament with the U.S. U-16s the following year. She then started four of five matches as the U.S. won the 2024 CONCACAF Women’s U-17 Championship. A torn meniscus after that tournament threatened her college debut, but she recovered in time to join North Carolina for preseason.
Trinity Armstrong Career
Early Career (2023–2024)
Armstrong’s first major senior-level recognition came through the United States youth national teams, beginning with the U-16 setup in 2023. Her club pathway included FC Dallas in the ECNL, where she earned All-American honors, and a brief preseason stint with Racing Louisville of the NWSL. These experiences helped her transition into college soccer as a highly decorated recruit.
At the University of North Carolina in 2024, Armstrong played and started 21 games as a freshman, scoring one goal. She contributed to a 19–2 record in the matches she appeared in, while the team went 3–3 when she was away at the 2024 FIFA U-17 Women’s World Cup. She returned to the Tar Heels in time for the ACC tournament, scoring a header and making a crucial goal-line clearance in a 2–1 comeback win over top-ranked Duke.
North Carolina Tar Heels Breakthrough (2024)
Armstrong’s 2024 season at North Carolina was the defining chapter of her pre-professional career. After the first round of the NCAA tournament, in which several starters were rested, she played every remaining minute and helped the Tar Heels concede only one goal across six games. North Carolina beat Wake Forest 1–0 in the final to claim its record 23rd national title and its first since 2012.
For her play, Armstrong was named second-team All-American and first-team All-ACC. TopDrawerSoccer wrote that she casually delivered one of the best defensive campaigns college soccer has seen from a freshman. Following the championship, she chose to forgo her remaining college eligibility and declared for the 2025 NWSL pathway.
San Diego Wave FC Era (2025–Present)
On January 16, 2025, San Diego Wave FC announced the signing of Armstrong to her first professional contract, a three-year deal running through 2028. At 17 years old, she was quickly viewed within the league as a possible successor to Naomi Girma, who departed for Chelsea ten days later. Sports Illustrated ranked her as the top NWSL prospect in her rookie class.
Armstrong made her professional debut with a stoppage-time appearance in the season-opening 1–1 draw with Angel City FC on March 16, 2025. On April 12, she made her first professional start, earning praise for her defensive work against Kansas City Current MVP Temwa Chawinga despite a 2–0 loss. After another start in a 4–1 win over Racing Louisville, she became a regular starter in central defense under head coach Jonas Eidevall.
On May 4, 2025, Armstrong scored her first professional goal, a stoppage-time winning header in a 2–1 home victory over Bay FC. She was named to the NWSL Team of the Month for May after recording a goal and an assist, becoming the youngest player ever to earn the honor. She finished her rookie regular season with 23 appearances, 18 starts, one goal, and more than 1,600 minutes played, helping the Wave finish sixth in the standings. In the playoff quarterfinals, she entered as an extra-time substitute and forced a point-blank save from Mackenzie Arnold, though San Diego fell 1–0 to the Portland Thorns.
Driving Style and Strengths
Armstrong is recognized for her composure on the ball, strong aerial ability, and intelligent positioning from the center-back position. Her partnership with San Diego’s coaching staff, including head coach Jonas Eidevall, has allowed her to step into a high defensive line and handle some of the league’s most dangerous attackers. Her early-career performances suggest a player equally comfortable in one-on-one defending and in build-up play from the back.
Notable Events and Milestones
Among her signature achievements are the 2024 NCAA national championship with North Carolina, a bronze medal at the 2024 FIFA U-17 Women’s World Cup, and her record-setting NWSL Team of the Month selection in May 2025 as the youngest player to receive the honor. Her first professional goal, a stoppage-time header against Bay FC, and her standout defensive performance against Temwa Chawinga are also early career-defining moments.

Although still early in her senior career, Armstrong has already collected significant team and individual honors across college, club, and international levels.

Armstrong helped the United States win the 2024 CONCACAF Women’s U-17 Championship, starting four of five games, before anchoring the back line at the 2024 FIFA U-17 Women’s World Cup, where she played every minute and helped her country keep four clean sheets in six matches. In college, her 2024 freshman campaign ended with a national title, a second-team All-American selection, and a first-team All-ACC nod.
Other Wins and Performances
At club level, Armstrong also won the Montaigu Tournament with the U.S. U-16s in 2023 and earned ECNL All-American honors during her time with FC Dallas. She is contracted with San Diego Wave FC through 2028 and is positioned as a foundational piece of the club’s defense for the foreseeable future.

2025 Season Performance
Trinity Armstrong’s rookie NWSL season with San Diego Wave FC has already exceeded most external expectations. After debuting in mid-March, she moved from substitute appearances to a starting role within weeks and became one of the most reliable young defenders in the league. Her 1,600-plus minutes across 23 regular-season games underlined her importance to head coach Jonas Eidevall’s system.
Key results included her first professional start against the Kansas City Current, her stoppage-time winning header against Bay FC on May 4, and her inclusion on the NWSL Team of the Month for May.

Looking ahead, Armstrong is signed through 2028 and is expected to remain a centerpiece of San Diego’s defense. With continued development alongside her coaching staff and veteran teammates, she is positioned to be a long-term starter for the Wave and a future candidate for the senior U.S. Women’s National Team.
