The Seattle Sounders signed forward Osaze De Rosario through 2025 on Thursday with club options for 2026 and 2027.
The 23-year-old Guyana international arrives from the Tacoma Defiance, where he leads MLS NEXT pro with eight goals through five matches. He also scored two goals in Tacoma’s 2025 U.S. Open Cup run.
De Rosario has appeared in two matches for the Sounders on short-term loans.
“Osaze’s path to the first team is another example of how our developmental system is designed to work,” general manager and chief soccer officer Craig Waibel said. “Osaze has taken full advantage of his time with our staff with Defiance. He is currently performing at a high level and is showing the kind of professional growth we value. We believe he has the tools to continue to improve and to contribute in MLS. We’re looking forward to seeing how he evolves within our environment.”
De Rosario is the son of MLS and Canada legend Dwayne De Rosario, a four-time MLS Cup champion and 2011 MLS MVP who scored 104 goals with five teams.
