Osaje De Rosario, son of Canadian Soccer Hall of Famer Dwayne De Rosario, has signed a new contract with the Seattle Sounders for the 2028-29 season that includes a 2029-30 club option.
The 24-year-old forward originally signed with the MLS team in May 2025, promoted from Seattle’s reserve Tacoma Defiance team. At the time, De Rosario was leading the MLS Next Pro League with eight goals in five games.
He won the Sounders’ first-ever Pathway Player of the Year award in 2025 after scoring 12 goals for Tacoma and five for Seattle.
De Rosario signed with Tacoma prior to the 2024 MLS Next Pro season. Previously, he played for York United FC (now Inter Toronto FC) in the Canadian Premier League from 2022 to 2023, scoring 19 goals and 6 assists in 57 games.
Before York, he spent time at the academies of Toronto FC and New York City FC, and made his first professional appearance with Ukrainian club Rukh Lviv.
Born in San Jose while his father played for the Earthquakes, De Rosario plays internationally for Guyana.
His younger brother, Adisa De Rosario, is a third-line goalkeeper for Toronto FC.
Dwayne De Rosario, now 47 years old, has played 81 games for Canada and scored 22 goals.
Named one of the top 25 players in MLS in 2020, he has scored 104 goals for San Jose, Houston Dynamo, Toronto FC (twice), New York Red Bulls and DC United.
A six-time member of the MLS Best XI, he was named MLS Most Valuable Player and won the Golden Boot Award in 2011. A four-time MLS Cup winner, he was named MLS Cup MVP twice (2001, 2007). A seven-time MLS All-Star, he also won the Supporters’ Shield and the US Open Cup.
Also Tuesday, Seattle signed new deals with Nouhou, Alex Roldan and Danny Musovski.
Nuhu and Roldan are under contract through the 2028-2029 season with a club option for 2029-2030, while Musovski is under contract for the 2027-2028 campaign with a club option for 2028-2029.
“Securing Nuhu, Alex, Danny and Osaje is an important step in maintaining continuity within our roster,” Seattle GM and chief football officer Craig Waibel said in a statement. “Nuhu and Alex have been key members of this group for many years and understand the standards that come with representing this club.
“Danny and Osaze showed last season that they can be influential attacking players in our league. Rewarding players for their dedication and performance to the team is a top priority for us and we are excited to keep this group together as we continue to progress towards our goals.”
