De Rosario currently leads MLS NEXT Pro this season with eight goals through five matches and scored two goals during Defiance's 2025 Lamar Hunt U.S. Open Cup run.

"Osaze's path to the First Team is another example of how our developmental system is designed to work," said Sounders FC General Manager & Chief Soccer Officer Craig Waibel. "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 signed with Tacoma prior to the 2024 MLS NEXT Pro season, scoring six goals in 22 appearances (13 starts) in his first year with the club while helping the team reach the MLS NEXT Pro Western Conference Semifinals.

"Osaze has earned this opportunity with the First Team," said Sounders FC Head Coach Brian Schmetzer. "His performance with Tacoma Defiance has been consistently strong since he joined the club last year. He's shown an admirable work rate and a real striker's instinct in front of goal. We're excited to integrate him into the squad and see what he can bring at the MLS level."
