Match ends, Tottenham Hotspur 1, Sunderland 0.
Tottenham maintained their unbeaten start to the Premier League season with a comfortable victory against winless Sunderland at White Hart Lane.
Spurs dominated but did not make the breakthrough until Harry Kane scored with their 22nd attempt on goal.
Papy Djilobodji failed to clear a Dele Alli header allowing Kane to poke home from point-blank range on 59 minutes.
Late on, Kane suffered a nasty ankle injury and Sunderland's Adnan Januzaj was sent off for a second booking.
A fourth defeat in five games means Sunderland are yet to win in the league under David Moyes.
The scoreline could have been worse for them but for outstanding goalkeeper Jordan Pickford, 22, who made a string of saves to keep his side in the game.
England striker Kane, who scored his second goal of the season, limped off the field after injuring his ankle with three minutes remaining and eventually left on a stretcher.
Aside from losing Kane, there was further injury worry for Spurs as England's Eric Dier and Belgium's Mousa Dembele were both substituted in the second half with what appeared to be hamstring injuries.
Moussa Sissoko was given his first start for Spurs since his £30m move on transfer deadline day and he joined Dembele and Victor Wanyama in a powerful midfield as Erik Lamela and Christian Eriksen dropped to the bench.
Tottenham completely dominated the game with 31 shots and 73.8% possession.
In the first half alone, they mustered 19 efforts with Kane, Son Heung-min and Toby Alderweireld going close.
Impressive South Korea winger Son was Spurs' best attacking force with five key passes and seven shots, though only two were on target.
The win was the perfect response after the disappointing midweek Champions League defeat by Monaco at Wembley and moves Spurs up to third in the table.
Blunt Black Cats
In contrast to the home side's dominance, Sunderland had just three shots in the first half.
The first came after 22 minutes as Jermain Defoe latched onto a long ball from Pickford but was unable to get his shot past Hugo Lloris.
Steven Pienaar had the best chance of the half just before the break as he met Januzaj's cross but his shot from six yards was cleared off the line by Kyle Walker.
The worry for the Black Cats is that striker Defoe managed just 13 touches in the match and only one of those came in Spurs' area.
Pickford had the most touches and his eight saves were vital in keeping the score respectable.
Moyes will have to do without Januzaj for the next match as the on-loan Manchester United winger was dismissed for a second booking in the space of 10 minutes. Having been cautioned for dissent, he saw red after fouling Ben Davies.
Man of the match - Son Heung-min (Tottenham)
What they said
Sunderland manager David Moyes: "Steven Pienaar had a great chance and we probably need to score any chance we get.
"Jordan Pickford is going to be a very good keeper. He has a lot of work to do at the moment, more than I'd like him to get. He will get better, he has a real good future ahead of him.
"We had a chance to clear the ball for the goal. That was a mistake and, of all the chances Tottenham got, that was a soft one and we gifted them that.
"It is a big job. I know how much is going to get better. All we can do is keep getting on the training field and making it better and I enjoy doing that."
Tottenham boss Mauricio Pochettino: "Sometimes it's difficult. In the end it was fair.
"We fought a lot and tried to score. I'm happy with the three points and it takes away the feeling from losing against Monaco.
"I want to create chances and play well - sometimes you need a lot of chances to score. Today we always tried to go forward. We feel disappointed because we created a lot of chances in the first half."
