SAN JOSE, Calif. — The San Jose Earthquakes have signed defender Jack Jasinski to a contract for the 2026 season with club options through the 2028-29 season.
“Jack is a promising player,” said Earthquakes Sporting Director and Head Coach Bruce Arena. “We are looking forward to seeing him develop in San Jose and believe he has the potential to have a productive career in Major League Soccer.”
Jasinski, 22, was selected in the second round (41st overall) in the 2026 MLS SuperDraft out of Princeton University, where he finished his collegiate career as a Second Team All-American, First Team All-Region and unanimous selection for the All-Ivy League First Team. He recorded a game-tying assist in the Earthquakes’ Feb. 11 preseason win over the Portland Timbers.
“I’m really excited to sign my first professional contract,” said Jasinski. “I’m grateful to the San Jose Earthquakes for their belief in me and thankful for everyone who has helped me get to this point. I’m looking forward to a great season.”
As a four-year starter at Princeton, Jasinski tallied 26 goal contributions (4g/22a) in 68 matches (65 starts). In 2025 when the Tigers doubled as regular-season and Ivy League tournament champions, the right back started all 19 games, with his team-leading six assists good for second in the conference as he was a Second Team All-American, First Team All-Region and unanimous selection for the All-Ivy League First Team.
In the 2024 campaign, Jasinski started all 18 games and led the Ivy League in assists (9), averaging 0.5 helpers per match to rank 15th in the nation individually. Three of those assists occurred during Princeton’s Ivy League Tournament run as they captured their first-ever title in school history. Jasinski would conclude both his junior and sophomore seasons on the All-Ivy League Second Team.
A native of Charlotte, North Carolina, and product of the Philadelphia Union Academy, Jasinski previously played with Philadelphia Union II and as invited to preseason with the Union's MLS First Team in 2022, seeing action in a friendly against FC Cincinnati.
