RIO DE JANEIRO (Interstat) — Fluminense delivered a stunning 6-0 victory over Sao Paulo on Thursday, emphatically defying pregame projections in the Carioca Série A season opener at Estadio Jornalista Mário Filho. Martinelli opened the scoring in the 16th minute, followed by Nonato just eight minutes later. The second half featured goals from John Kennedy, Agustín Canobbio and Kevin Serna in a dominant display. The result was a shock after statistical models heavily favored Sao Paulo to win. The lopsided defeat leaves Sao Paulo with a loss in both this competition and across all season matches, while Fluminense starts its campaign with a perfect record.
