Substitute Mikel Merino scored in the first minute of second-half stoppage time to lift Spain into the World Cup quarterfinals with a 1-0 victory over Portugal in the Round of 16 clash in Arlington, Texas.

Merino’s goal six minutes after his insertion takes La Roja to their first quarterfinals since winning their only World Cup title in 2010. They will next play in Inglewood, California, against Belgium, a 4-1 winner against the United States later.

Portugal’s loss likely marks the last World Cup appearance for 41-year-old attacker Cristiano Ronaldo, who scored three goals at his record-tying sixth World Cup.

Unlike Argentina’s Lionel Messi, who won the 2022 tournament in his fifth appearance and reached the 2014 finals, Ronaldo will complete his sixth World Cup without reaching a final. Portugal’s best showing during his tenure came via a semifinal run in his 2006 tournament debut.

Merino’s winner, his first goal of the tournament after scoring six for Spain in qualifying, came after what was a largely uneventful second half, and from a seemingly innocent restart well beyond the penalty arc.

Fellow substitutes Ferran Torres and Fabian Ruiz combined through the middle to play Merino into the penalty area alone, where his low finish beat the charging Diogo Costa inside the left post.

Dormant for most of the second half, Portugal’s attack finally showed signs of life in search of a miracle equalizer. Bernardo Silva came closest to leveling with a header narrowly over the bar six minutes into added time.

But it would have been undeserved, with Portugal barely testing goalkeeper Unai Simon. He finished with only two saves, keeping Spain the only team in this tournament yet to concede.

Spain had the better start. Mikel Oyarzabal missed wide in the ninth minute after an excellent early attack solved Portugal’s offside trap, and eight minutes later, Lamine Yamal and Alex Baena forced Costa into a double save.

Portugal grew into half. Ronaldo forced Simon into a leaping but ultimately comfortable save in the 37th minute, and four minutes later, Nuno Mendes’ thunderously struck attempt deflected off Pedro Porro and then the crossbar. (Field Level Media / Reuters)
