Visiting centre-half David Brekalo was left unmarked as he headed home Eduard Atuesta's free-kick with just seven minutes gone. Paraguay midfielder Braian Ojeda completed the rout in the 73rd minute as his header squeezed between Gunn and the near post from another Atuesta set piece. At the other end, Gunn's opposite number, Canada's Maxime Crepeau, produced several fine saves, a couple denying Timo Werner a scoring debut for San Jose after the Germany striker's move from RB Leipzig. San Jose are fourth in the overall table, with Nashville leading ahead of Argentina forward Lionel Messi's Inter Miami. Gunn's side next host LA Galaxy, who are ninth in the Eastern Conference, on Sunday.
