Third-tier Ourense produced the first big upset of the Spanish Copa del Rey, knocking La Liga side Oviedo out of the first round with a 4-2 win.

Ourense was seconds from elimination after Josip Brekalo and then Luka Ilic put Oviedo ahead twice, but Omar Ouhdadi and Aymane Jelbat twice canceled out the lead, with Jelbat heading in seconds from time.

Ourense was the better side in extra time. Ouhdadi put them ahead in the 98th minute and Amin Abaradan made it 4-2 with a 114th-minute penalty. It could have been 5-2 had Adrian Guerrero converted a last-kick penalty.

Fifth-tier Constancia took La Liga's bottom team Girona to extra time before losing 3-2 after 120 minutes.

Elsewhere, top-flight sides had few problems against lower-league rivals. Valencia overcame a difficult first half to win 5-0 away to Maracena. Sevilla came from an early goal down to win 4-1 in Toledo, while Real Sociedad made hard work of its 3-0 win away to sixth-tier CD Negreira. Getafe had no such issues, defeating Inter de Valdemoro 11-0.
