While there remains a chance of them pushing their way into the top-six battle it is an increasingly remote one, with injuries and a frustrating end to the January transfer window taking their inevitable toll.
There have been some major highs and some impressive performers across a campaign, though it is one that will end with some regret given the outstanding position the club found itself in at the turn of the year.
So who has stood out over the course of the season and who might have a big summer decision to make depending on how the next six weeks or so go? We calculated our average player ratings from the season so far to find out more. We set a minimum of five senior appearances, to avoid any unfair judgements or major anomalies.
5. BAILEY WRIGHT
5.9 Wright struggled for regular starts through the first half of the season, and so producing a consistent run of form was always going to be difficult. A major presence behind the scenes, he also stepped in with little match fitness to play a part in some crucial wins to keep Sunderland away from trouble. Might have a big decision to make on his longer-term future in the summer, as he has made clear he still wants to be playing regularly. Photo: Frank Reid
6. TRAI HUME
6.3 Had to be patient as Lynden Gooch started the season in excellent form, but was nothing short of a revelation after the World Cup break. Has a great leap, loves a challenge and is comfortable enough on the ball to drift into midfield when required. Has understandably found it tougher in recent weeks as a very heavy schedule has taken its toll on the young squad as a whole, but a big part of the future. Photo: Frank Reid
7. AJI ALESE
6.2 Has had a similar campaign to Dennis Cirkin, with a lot of positives and good performances but some injury frustration. It’s to Alese’s credit that he’s made a positive contribution in his first season of senior football, and having had to be patient in waiting for minutes earlier in the season. And - he’s often done it somewhat of out position, having rarely featured in central defence where has mostly played in his youth. Photo: FRANK REID
8. CORRY EVANS
6.2 A consistent performer whose importance has been underlined in his absence through injury. A calming presence who protects the defence well, and Sunderland need another of his ilk in the summer window - the last few weeks have made that clear. Photo: Frank Reid
