Sam Allardyce handed Premier League debuts to three youngsters in the 2-2 draw with Watford at Vicarage Road.
Winger Rees Greenwood and left-back Tommy Robson were in from the start, with George Honeyman on as a second-half sub.
Richard Mennear takes a look at how they got on:
Left-back who has been in and around the first-team picture for the last 18 months, without being given the opportunity to make his debut.
Unfazed Robson, who is under contract until the summer of 2018, settled well at Vicarage Road, keeping it simple at left-back.
Ten minutes in he showed his attacking intent.
Robson burst forward down the left-flank, played the ball to Dame N'Doye but the striker couldn't control the ball.
N'Doye was proving the best outlet for the 20-year-old full-back though, with Robson targeting him with long balls upfield.
Defensively, he was cool and calm in possession and made a couple of interceptions at the back to ensure Sunderland went in at the break with their clean sheet intact.
Didn't look out of place at this level, he was the pick of the Sunderland debutants.
The stand-out player for the Under-21s this season and that has rightly seen the 20-year-old winger earn an England Under-20s call-up.
Composed start to proceedings and he didn't look out of place on the left-wing, with Duncan Watmore on the right and Jeremain Lens behind N'Doye.
Tricky play inside the penalty area in the 27th minute won Sunderland a corner.
Switched flanks with Watmore after half an hour of the first half, with Sunderland struggling to create chances.
Thirty seven minutes in Greenwood cuts inside from the left flank, drifted past two Watford defenders before laying the ball off to Jack Rodwell, the former Manchester City man's shot inches wide of right-hand post.
He played a key role in the opening goal 39 minutes in.
Sunderland took the lead through Rodwell, slotting home Jeremain Lens' cross. Lens was teed up by Greenwood's pass out wide, to keep the move flowing.
Showed flashes, he was subbed after 52 minutes.
The 21-year-old made his first-team debut as a late substitute in last season's FA Cup defeat at Bradford and penned a new 12-month contract at the Stadium of Light last month.
The attacking midfielder came on for Greenwood just seven minutes after the re-start to make his Premier League debut and slotted into the role vacated by his Under-21 teammate.
He struggled to have a major impact on though and didn't see enough of the ball in dangerous areas.
Worked hard but Allardyce would have hoped for more attacking intent.
