Ariel Lassiter Bio
Ariel Daniel Lassiter Acuña (born 27 September 1994) is a Costa Rican professional footballer who plays as a winger for Major League Soccer club Portland Timbers and the Costa Rica national team. Standing 178 cm tall, the left-footed attacker is known for his work rate, crossing ability, and eye for goal in the final third of the pitch. After beginning his professional career in Sweden in 2014, Lassiter has spent most of his club career in Major League Soccer, with stints in his native Costa Rica in between.
The son of a former professional footballer, Lassiter grew up between Costa Rica and the United States, an upbringing that shaped his dual eligibility before he committed to Costa Rica at the senior level. He has represented Los Ticos at the 2021 CONCACAF Gold Cup and continues to feature for the national team.
Early Life and Background
Ariel Lassiter was born on 27 September 1994 in Turrialba, Costa Rica, where his father Roy played club football for A.D. Carmelita. The Lassiter family later relocated to the United States after Roy signed with the Tampa Bay Mutiny of Major League Soccer, eventually settling in Temecula, California when Ariel was 13 years old.
In Temecula, Lassiter attended Great Oak High School and played on the school soccer team for four years, captaining the side for two seasons. His performances earned him several accolades, including being named the two-time Inland Empire High School Player of the Year.
After high school, Lassiter played college soccer for the Cal Poly Mustangs. In his freshman season, he tallied five goals and four assists in 21 appearances and earned a place on the Big West Conference All-Freshman team. He left Cal Poly after that single season to turn professional.
Path to Professional Football
Lassiter’s earliest professional experience came abroad. In July 2014, he signed with GAIS of the Swedish Superettan, making his debut on 9 August 2014 in a 2–1 win over Husqvarna FF. He opened his goalscoring account two weeks later in a 2–0 victory against Varbergs BoIS and finished his first professional season with one goal from 12 appearances.
His move to the United States came in January 2015, when he joined LA Galaxy II of the United Soccer League. With Galaxy II, he recorded 11 goals and one assist in 21 regular-season games, helping the reserve side reach the USL final, where they fell 2–1 to the Rochester Rhinos. He also made a single appearance for the LA Galaxy first team in MLS that season, coming off the bench against the Houston Dynamo.
Ariel Lassiter Career
Early Career (2014–2015)
Lassiter’s professional journey began at GAIS in Sweden during the second half of 2014, where limited but consistent minutes gave him his first taste of senior football. The experience abroad prepared him for a return to North America, where his family ties to Major League Soccer quickly opened the door to the LA Galaxy organization.
His first full professional season came with LA Galaxy II in 2015, a campaign that established him as a dangerous goalscorer in the USL. With 11 goals and one assist in the regular season, plus four more goals in the playoffs, Lassiter emerged as one of the reserve league’s most productive young attackers and earned a first-team contract with the Galaxy in March 2016.
LA Galaxy Era (2015–2018)
Lassiter spent four seasons tied to the LA Galaxy organization. After impressing with Galaxy II in 2015, he was promoted to a first-team deal in March 2016, splitting time between the senior squad and the reserves. He battled a back injury during the middle of that season but returned to score nine goals in 16 games for Galaxy II, before featuring in the Galaxy’s final two regular-season matches of the year.
The 2017 season produced his breakthrough at the MLS level. On 14 June 2017, he scored his first goal for the Galaxy senior team, helping LA defeat Orange County SC 3–1 in the U.S. Open Cup. He followed it with another goal in the next round before netting his first career MLS goal on 23 July in a 4–3 loss to the New England Revolution. He ended the year with one goal in 14 MLS appearances, two goals in the Open Cup, and five goals with Galaxy II.
In 2018, his role shifted primarily to Galaxy II, where he produced five goals and four assists in 12 appearances, while managing seven substitute league outings and two U.S. Open Cup goals with the first team. On 26 November 2018, the Galaxy declined his contract option for the 2019 season, ending his time in Los Angeles.
Alajuelense Era (2018–2020)
On 18 December 2018, Lassiter returned to his home country, signing with Liga Deportiva Alajuelense. He debuted in January 2019 and quickly adapted to Costa Rican football, finishing the Clausura 2019 with three goals in 16 matches. He found his scoring touch during the 2019 Apertura, registering 12 goals and five assists in 20 regular-season appearances as Alajuelense finished top of the table.
Lassiter helped Alajuelense reach the Apertura 2019 final, where they fell 2–0 to C.S. Herediano, and then featured in both legs of the subsequent grand final, which Herediano won 5–4 on penalties after a 2–2 aggregate. In the Clausura 2020, he added eight goals and nine assists in 18 league matches before signing a new contract extension in May 2020 that ran through 2023.
Houston Dynamo Era (2020–2021)
On 17 August 2020, Lassiter returned to Major League Soccer on loan to the Houston Dynamo. He opened his account immediately, scoring twice off the bench on 2 September in a 3–0 win over Minnesota United. He finished his debut MLS campaign with three goals and one assist in 16 appearances, even as Houston finished bottom of the Western Conference.
The Dynamo exercised their purchase option on 1 December 2020 in a reported deal worth around $400,000. In 2021, he made 19 appearances, but Houston again finished last in the West, leading to his departure via trade.
Inter Miami Era (2022–2023)
On 16 December 2021, Lassiter was traded by Houston to Inter Miami in exchange for $100,000 in General Allocation Money. The move placed him within an ambitious Inter Miami project, though his role during the 2022 and 2023 seasons remained largely as a rotational winger.
CF Montréal Era (2023–2024)
On 12 April 2023, Lassiter was traded, along with teammate Bryce Duke, to CF Montréal in exchange for Kamal Miller and $1.3 million in General Allocation Money. His time in Montréal added further Canadian experience to his MLS résumé as he continued to operate primarily on the wing.
Chicago Fire Era (2024)
On 14 August 2024, Lassiter was traded to the Chicago Fire in exchange for up to $150,000 in General Allocation Money. His short stint in Chicago provided another stop along a peripatetic MLS journey.
Portland Timbers Era (2024–Present)
On 23 December 2024, Lassiter signed with the Portland Timbers via free agency, taking on a winger role at Providence Park. The move to Portland marked a fresh chapter as he sought to cement a regular starting place heading into 2025.
Playing Style and Strengths
Lassiter is a left-footed winger who combines direct running with intelligent movement off the ball. His strengths include crossing from wide areas, timing late runs into the box, and contributing goalscoring numbers from midfield, as evidenced by his double-digit tallies during the 2019 Apertura with Alajuelense. He has consistently produced assists alongside his goals, reflecting an unselfish approach in the final third.
Notable Events and Milestones
Among Lassiter’s most memorable career moments is his debut brace for the Houston Dynamo, when he came off the bench to score twice against Minnesota United on 2 September 2020. He also netted his first MLS goal for the LA Galaxy on 23 July 2017 against the New England Revolution and scored his first senior international goal at the 2021 CONCACAF Gold Cup against Guadeloupe.
Ariel Lassiter International Career
Born in Costa Rica but raised in the United States, Lassiter held dual eligibility. He represented the United States U-23 national team twice in 2015 friendlies before switching allegiance to the Costa Rica U-23 side and appearing at the 2015 Toulon Tournament.
He made his senior debut for Costa Rica on 22 March 2019 in a friendly against Guatemala, replacing Waylon Francis in the 63rd minute. Lassiter was included in Luis Fernando Suárez’s squad for the 2021 CONCACAF Gold Cup, where he scored his first senior international goal on 12 July in a 3–1 group-stage win over Guadeloupe. He finished the tournament with one goal and one assist in four appearances as Costa Rica reached the quarterfinals.
Ariel Lassiter Family
Family Background and Football Lineage
Ariel Lassiter is the son of Roy Lassiter, a former professional footballer who played for A.D. Carmelita in Costa Rica and later signed with the Tampa Bay Mutiny of Major League Soccer. Roy’s career abroad shaped the family’s move to the United States and ultimately influenced Ariel’s development as a young player in Southern California.
Personal Life
Beyond his football career, Lassiter has kept his personal life largely private, with limited public details about relationships or residence beyond his club commitments.
2025 Season Outlook
Heading into 2025, Ariel Lassiter is expected to compete for a regular role on the wing with the Portland Timbers following his December 2024 free-agent signing. The Timbers will look to his experience across multiple MLS clubs and a season of double-digit scoring in Costa Rica to provide attacking depth and creativity.
For Lassiter, the campaign represents an opportunity to establish consistency after several short stints around the league between 2022 and 2024. A strong start in Portland could position him for more frequent call-ups to the Costa Rica national team as Los Ticos build toward future CONCACAF competitions.
With a full preseason at Providence Park and familiarity with the league, Lassiter’s blend of crossing, finishing, and work rate gives the Timbers a versatile option on either flank in 2025.
