VIÑA DEL MAR, Chile (Interstat) — Substitute Álvaro Ramos scored the lone goal late in the first half, lifting Deportes Iquique to a 1-0 upset victory over Everton on Sunday in a Chilean Primera División match at Estadio Sausalito.

The result, which defied pregame projections that heavily favored the home side, handed Iquique a winning start to its domestic campaign while leaving Everton searching for answers after an opening-day defeat.

The match’s decisive moment arrived in the 44th minute. The play was initiated by forward Alan Medina, who was later credited with an assist after his involvement in the buildup. The move culminated with a decisive finish from Ramos, who had entered the match as a substitute and made an immediate impact by breaking the deadlock just before halftime.

The goal stood as the game-winner in a contest characterized by physical play and frequent interruptions. The officiating crew was busy throughout, distributing seven yellow cards across both teams.

The first half was particularly fraught, with four players booked. Iquique’s Medina received a caution in the 16th minute, followed by Everton’s Sebastián Sosa in the 24th. Iquique’s Agustín Venezia was shown a yellow card in the 28th minute, and teammate César González was booked in first-half stoppage time.

The second half saw the disciplinary trend continue. Everton’s Luis Casanova was cautioned in the 84th minute, and a flurry of cards came in the final moments of stoppage time, with Iquique’s Leandro Requena and Marcos Gómez both being booked.

The final score was a surprise based on statistical models. Interstat’s game simulator had projected a 1-1 draw, while its ELO rating system gave Everton a 73.80 percent probability of securing a victory. Instead, Iquique’s organized defense and clinical finishing in a key moment secured all three points for the visiting squad.

With the victory, Deportes Iquique begins its season with one win and zero losses in the Primera División. Across all competitions, the team’s record also stands at one win and zero losses. Everton, conversely, starts its league campaign with zero wins and one loss. The club’s record in all competitions also falls to zero wins and one loss.
