Spain advances to quarterfinals in Portugal star Ronaldo's potential final World Cup game

Mikel Merino scored in the first minute of second-half stoppage time, and Spain beat Portugal 1-0 on Monday to end the World Cup career of superstar Cristiano Ronaldo.

Merino had just been knocked down, and a foul was called. While Portugal's Bernardo Silva argued, Merino played the ball back in, ran toward the goal and easily beat goalkeeper Diogo Costa after taking a pass from Ferran Torres.

Spain advanced to the quarterfinals for the first time since winning its only World Cup title in 2010. La Roja will play either the United States or Belgium on Friday in Inglewood, California.

Ronaldo was trying to get Portugal to the quarterfinals in a second consecutive tournament for the first time. Instead, the career on soccer's biggest stage is over for the all-time leader in international goals (146) and appearances (233).
