Portugal veteran Ronaldo found the net twice in the first 12 minutes at Al Awal Park before completing his treble after the interval.

Sadio Mane teed up Ronaldo's third finish, as well as an 18th-minute strike from Otavio, who returned the favour for the Senegal international to score on the stroke of half-time.

Mohammed Al Fatil added a late sixth as Al Nassr recorded its seventh straight league win since its 8 March (AEDT) loss against Al Raed, moving it back within nine points of leader Al Hilal.

Jorge Jesus's Al Hilal swept Al Tauwoon aside in a 3-0 away triumph for its fourth straight victory across all competitions.

Talisman Aleksandar Mitrovic opened the scoring at King Abdullah Sport City Stadium before Saud Abdulhamid and Saleh Alsherhi wrapped up a win that kept Al Hilal in charge of the title race.

There was no such fortune for fifth-placed Al Ittihad as it fell to a third straight defeat in all competitions after a 3-1 loss away against Abha.

Jota levelled after Grzegorz Krychowiak's 57th-minute penalty, only for Hassan Al-Ali and Fabian Noguera to power hosts Abha to a comfortable win.
