A solitary goal from Luiz Suarez was enough for Uruguay to get past Saudi Arabia in Rostov.
The Barcelona man was happy to sweep home at the goalmouth after a Carlos Sanchez cross from a corner sailed over Saudi goalkeeper Mohammed Al-Owais’ attempted punch and found the Barcelona striker unmarked at the far post.
Both teams struggled to create chances in the second half, with half-chances the best either could produce.
Cavani missed a vital chance four minutes from time when a fallen defender allowed him a one-on-one chance with Al-Owais at the top of the box but Saudi keeper did well to get a foot on the PSG man’s effort and keep it out.
The win gives Uruguay six points from two matches, trailing leaders Russia — also with six points — only on goal difference.
The Saudis and Egyptians have yet to collect a point.
Uruguay will finish group play against the Russians on Monday in Samara with Saudi Arabia playing Egypt that same day in Volgograd.
