Late Murphy strike seals key win back in 2008.
The Black Cats came out on top in a five-goal Wear-Tees derby as Daryl Murphy’s injury-time winner secured Sunderland’s Barclays Premier League status.
Danny Higginbotham and Michael Chopra also scored for the hosts after Tuncay had given Boro the lead.
Afonso Alves looked like he had earned the Teesiders a point but Murphy headed home at the death to win it.
Roy Keane’s side started slowly and were behind inside the opening five minutes as Tuncay found space in behind the Sunderland defence and slotted past Craig Gordon.
Higginbotham replied immediately for the Black Cats when he guided Danny Collins’ cross beyond Brad Jones in the Middlesbrough goal.
Chopra put the hosts in a commanding position on the stroke of half-time after he latched on to Liam Miller’s long ball and smashed a left-footed strike in off the underside of the bar.
Alves scored what looked to be the equaliser 15 minutes from time as he slotted home after former Black Cat, Julio Arca, saw his shot deflect into the path of the Brazilian.
Sunderland showed great desire to bounce back and got their reward in injury time when Murphy rose to head Leadbitter’s near-post corner home.
When news came through of Birmingham’s draw at Liverpool, which meant the Black Cats were safe, the majority of the 45,059 crowd inside the Stadium of Light were on cloud nine.
Sunderland: Gordon, Whitehead, Nosworthy, Higginbotham, Collins, Edwards (Leadbitter, 60), Reid, Miller, Richardson, Chopra (Murphy, 85), Jones.
