After his two-goal show against Charlton, the little striker was again a lively presence in attack, setting up Robbie Keane to put us ahead on 37 minutes.
The home side battled gamely but did not really look like snatching a leveller until substitute Daryl Muprhy plotted a route into our penalty area and shot low from close range past Paul Robinson in the final minute. When three minutes stoppage time was flashed up, the boys pushed forward in search of a winner - the best chance falling to Jermaine Jenas who shot over from penalty spot range.
"It is unbelievable, I am gutted," said Jermain afterwards. "When you are winning 1-0 and look at the clock and it says 89 minutes, you think you should win and when they scored it was so hard to take. You can't come back from it.
"It is not the first time it has happened, but we need to pick ourselves up now and get ready for the Wigan game."
Jermain acknowledged that the team struggled to find any fluency in their game after the fine show against Charlton, but pointed out the pitch was not condusive to a passing display.
"The pitch was hard to play on, it cut up early on and it was difficult to pass the ball. We did well with the goal, it was a great ball from Michael and I stayed onside to cross for Robbie.
"I thought 'a goal early on, that is good for us, just keep it going', then for them to score so late is really hard for the boys," he continued, before reflecting on his own contribution.
"I thought I worked really hard, Sunderland are a physical side so it was always going to be diffuclt for me and Robbie. I am so disappointed, if we had won we would have created a gap and everyone is talking about that.
"I suppose you have just got to look forward now and get ready for Wigan. We didn't lose, Sunderland played alright, but we are just frustrated."
Asked to sum up his mood after Sunderland's late revival at the Stadium of Light, the word 'gutted' quickly came through the lips of Jermain Defoe.
