After leaving Atlanta United at the end of the 2022 MLS season, Martinez signed for Inter Miami and while he did find his footing after an injury-laden ending to Atlanta, the club opted against keeping him. That was despite the forward netting 11 goals in 23 appearances while being limited to just 13 starts for the club.
He was traded to CF Montreal and while he managed to contribute to 14 goals in 26 appearances, the club declined to take up the option to extend his time by another year. That saw him sign for the San Jose Earthquakes as a free agent in January 2025 just before the start of the 2025 MLS season.
The 31-year-old signed a one-year contract with the club and bolsters the Quakes’ front line even further after their blockbuster trade for RSL star striker Cristian "Chicho" Arango.
