Standing 1.78 m (5 ft 10 in) tall, he wears the number 7 shirt for Portland and operates primarily from wide attacking positions. His career has taken him across the United States, Costa Rica, and Sweden, giving him broad experience in multiple footballing cultures.
Born in Costa Rica and raised in the United States, Lassiter initially represented the United States at youth level before switching his allegiance to Costa Rica.

His journey from youth soccer in California to professional leagues in Europe and the Americas reflects a steady climb built on consistent goal-scoring output.
Early Life and Background
Ariel Daniel Lassiter Acuña was born on 27 September 1994 in Turrialba, Costa Rica. His father, Roy Lassiter, was a professional footballer who played for A.D. Carmelita in Costa Rica, embedding the sport into the family from an early age. When Roy signed with the Tampa Bay Mutiny of Major League Soccer, the Lassiter family relocated to the United States.
The family later settled in Temecula, California, where Ariel was 13 years old. He attended Great Oak High School and played on the school soccer team for four years, captaining the side for two of those seasons. His high school performances earned him recognition as a two-time Inland Empire High School Player of the Year, highlighting his standing as one of the top young players in the region.
After high school, Lassiter played college soccer for the Cal Poly Mustangs. In his freshman season, he recorded 5 goals and 4 assists across 21 appearances, a contribution that earned him a place on the Big West Conference All-Freshman team. He departed Cal Poly after that single season to begin his professional career.
Path to Professional Soccer
Lassiter’s youth career began with Albion SC from 2009 to 2013, a period during which he developed the technical foundation that would later define his play as a winger. His standout college freshman year with Cal Poly attracted professional attention, and in July 2014 he signed his first professional contract with GAIS of the Swedish Superettan, marking his transition from youth and college soccer to the senior ranks.
At GAIS, Lassiter made his professional debut on 9 August 2014, playing 70 minutes in a 2–1 win over Husqvarna FF. Two weeks later, on 23 August, he scored his first professional goal in a 2–0 win against Varbergs BoIS. He finished his first season abroad with one goal from 12 matches, a modest but encouraging beginning to his senior career.
In January 2015, Lassiter returned to the United States and signed with LA Galaxy II of the United Soccer League. He made his debut for Galaxy II on 22 March 2015 and scored his first goal for the club on 11 April, helping Los Dos to a 3–1 win over Sacramento Republic. The stage was set for his rise through the LA Galaxy system.
Ariel Lassiter Career
Early Career (2014–2015)
Lassiter’s early professional phase was split between GAIS in Sweden and LA Galaxy II in the United States. His stint at GAIS introduced him to senior football in Europe, while his move to Galaxy II provided a clear pathway into the LA Galaxy organization. The contrast between European and American soccer helped shape his adaptability as a young winger.
His first full season with Galaxy II in 2015 proved highly productive. Lassiter scored 11 goals and added 1 assist across 21 regular-season games, helping Los Dos qualify for the playoffs. He added four more goals in the postseason as Galaxy II reached the USL final, where they fell 2–1 to the Rochester Rhinos. He also made one senior-team appearance for the LA Galaxy first team in 2015, coming off the bench in a 3–0 MLS loss to the Houston Dynamo on 25 July.
LA Galaxy Era (2015–2018)
On 5 March 2016, the LA Galaxy announced that Lassiter had signed a first-team contract, formalizing his promotion to the senior squad. He began the season with Galaxy II, scoring twice in a 2–0 win over Arizona United on 26 March, before earning his first MLS start a week later in a 0–0 draw with the Vancouver Whitecaps. A back injury sidelined him for two months, but he returned to play out the Galaxy II season, scoring 9 goals with 1 assist across 16 matches.
The 2017 season saw Lassiter split time between the Galaxy first team and Galaxy II. On 14 June 2017, he scored his first goal for the senior team in a 3–1 U.S. Open Cup win over Orange County SC, and on 23 July he netted his first career MLS goal in a 4–3 loss to the New England Revolution. He finished 2017 with 1 goal from 14 MLS appearances, all as a substitute, along with 2 goals in 3 Open Cup matches and 5 goals across 9 Galaxy II games.
In 2018, Lassiter primarily featured for Galaxy II, recording 5 goals and 4 assists from 12 appearances. With the first team, he made 7 substitute league appearances and played twice in the U.S. Open Cup, scoring 2 goals. On 26 November 2018, the Galaxy declined his contract option for 2019, ending his time in the organization.
Alajuelense Era (2019–2020)
On 18 December 2018, Lassiter signed with Costa Rican club Liga Deportiva Alajuelense, returning to the country of his birth. He debuted on 16 January 2019 in a 3–3 draw against C.F. Universidad de Costa Rica and scored his first goal for the club on 27 February in a 4–2 win over Cartaginés. He closed his first Clausura with 3 goals from 16 matches.
His form peaked during the 2019 Apertura, when he scored 12 goals and added 5 assists across 20 regular-season appearances, helping Alajuelense finish top of the table. In the playoffs, Lassiter helped Los Leones reach the final, where they lost 2–0 to C.S. Herediano. Herediano then won a two-legged grand final 5–4 on penalties after a 2–2 aggregate. In the 2020 Clausura, he registered 8 goals and 9 assists from 18 matches, taking his Alajuelense totals to a strong body of work before departing. On 4 May 2020, he signed a new contract with Alajuelense running through 2023.
Houston Dynamo Era (2020–2021)
On 17 August 2020, Lassiter returned to MLS on loan with the Houston Dynamo, who sent $50,000 in general allocation money to the LA Galaxy to acquire his MLS rights. He made an immediate impact, scoring twice off the bench on 2 September to fuel a 3–0 win over Minnesota United. He finished the shortened 2020 season with 3 goals and 1 assist from 16 appearances.
On 1 December 2020, Houston exercised its purchase option to make the move permanent, reportedly for a transfer fee of around $400,000. In his second season in 2021, Lassiter made 19 appearances as the Dynamo again struggled, finishing last in the Western Conference for the second straight year.
Inter Miami, CF Montréal, and Chicago Fire (2022–2024)
On 16 December 2021, Lassiter was traded by Houston to Inter Miami in exchange for $100,000 in General Allocation Money, beginning a stretch of frequent moves. On 12 April 2023, he was traded alongside teammate Bryce Duke to CF Montréal in exchange for Kamal Miller and $1.3 million in General Allocation Money, continuing his path through the league. On 14 August 2024, he was traded to the Chicago Fire for up to $150,000 in General Allocation Money, rounding out a busy three-year period in MLS.
Portland Timbers Era (2025–Present)
On 23 December 2024, Lassiter signed with the Portland Timbers via free agency, beginning a new chapter in his MLS career. He joined a club aiming to retool its attack and provide a versatile winger capable of contributing goals and assists. The move to Portland offered him an opportunity to settle into a stable environment after several trades.
At Portland, Lassiter wears the number 7 shirt and is expected to feature in wide attacking positions. His track record of double-digit goal contributions in Costa Rica and steady production in MLS gives the Timbers a proven offensive option. The 2025 season represents a chance to establish long-term roots in a single project.
Driving Style and Strengths
Ariel Lassiter operates as a winger who combines direct attacking play with a willingness to track back and contribute defensively.

Across his time at Alajuelense, he demonstrated the capacity to combine goal-scoring with playmaking, evidenced by his tallies of 20 goals and 14 assists across 38 league appearances in Costa Rica.
Notable Events and Milestones
One of the defining moments of Lassiter’s career came during the 2019 Apertura in Costa Rica, when his 12 goals and 5 assists powered Alajuelense to first place in the regular season. His two-goal debut for the Houston Dynamo against Minnesota United in September 2020 also stands out as a signature MLS arrival moment. In international football, he scored his first senior goal for Costa Rica on 12 July 2021 in a 3–1 win over Guadeloupe at the CONCACAF Gold Cup.

Ariel Lassiter Family
Family Background and Soccer Lineage
Ariel Lassiter was born into a footballing family, with his father Roy Lassiter being a professional footballer who played for A.D. Carmelita in Costa Rica. Roy’s move to the Tampa Bay Mutiny of Major League Soccer was the catalyst for the family’s relocation to the United States, where Ariel would grow up and begin his youth career. The connection to professional football through his father provided Ariel with early insight into the demands of the sport at the highest level.
Personal Life
Ariel Daniel Lassiter Acuña splits his professional life between the United States and Costa Rica, with Portland serving as his current base after signing with the Timbers in December 2024. He holds dual eligibility through his Costa Rican birth and his upbringing in California, and he ultimately chose to represent Costa Rica at senior international level beginning in 2019. Beyond his career, details of his personal life remain limited in publicly available sources.
2025 Season Performance
The 2025 season marks Ariel Lassiter’s first full campaign with the Portland Timbers after signing in December 2024. Joining the club via free agency, he steps into a wide-attacking role where the Timbers will look to him for both goals and creative output. His experience across MLS, the USL, and Liga FPD gives him a versatile profile that suits a team aiming to refresh its attacking options.
Lassiter’s most recent productive stretch came with Alajuelense, where he produced 20 goals and 14 assists across the 2019 Apertura and 2020 Clausura combined. Bringing that kind of end product back to MLS represents a significant opportunity, both for him and for the Timbers’ playoff ambitions. Early-season form will likely determine how quickly he earns a regular starting role under the Portland coaching staff.
Heading into the rest of 2025, the outlook for Lassiter centers on establishing himself as a consistent contributor in Portland’s attack. If he can recapture the scoring touch he showed in Costa Rica while adapting to a new tactical setup, he has the tools to be a key piece of the Timbers’ push for a return to the MLS postseason. The combination of familiarity with the league and hunger from a fresh start positions him well for a productive year.
