Al-Owais - winning only his second cap after replacing Abdullah Al-Muaiouf in goal - completely missed a floated Carlos Sanchez corner and Suarez tapped in his 52nd global goal unmarked at the back post.
It was the Barcelona striker's 100th cap for his nation, and he marked it with a 52nd goal, a fantastic return for a world-class hitman.
Suarez capitalised on a mistake by opposition goalkeeper Mohammed Al-Owais to net what proved to be the victor after 23 minutes, but it was far from the convincing display that Uruguay were expected to produce. It wasn't the most compelling performance from Uruguay, which struggled in the attack yet again, but you can't argue with back-to-back clean sheets and two wins to start the tournament.
While Uruguay has done just enough to get past two lackluster opponents in its two Group Stage wins, there's a sense that we haven't seen the best of the South American side, that is one of just five countries to have won the World Cup a few times.
"We are more than proud because we've reached the knockout stage at three successive World Cups". They will face each other on Monday in Samara with first place in Group A on the line. "That's the World Cup for you though and we are obviously delighted with how we have performed so far to progress".
"Of course we demand a lot more from this type of player", Tabarez said at his post-match press conference.
Hattan Bahebri's ambitious 25-yard effort three minutes later forced Fernando Muslera to tip over his bar, before the winger got in ahead of his man to meet Yaseer Al-Shahrani's looping cross three minutes later but was just unable to keep his shot down. Saudi put up a good fight and performed well, although they never really troubled the Uruguay defence, they kept the ball well and limited Uruguay's attacking prowess.
"They did that very well and we have to respect them".
"I do fancy them in this tournament", said Neville. "Unfortunately we didn't create the opportunity we needed to equalize".
"We wanted to win and to progress to the knock-out stage and this game simply showed how hard it is".
"The difference between the performance in the first game and this game is enormous", Pizzi said.
