Made a good save from Jarvis' shot to prevent an equaliser, but otherwise went untested for the large part until he showed great reflexes to thwart Vaz Te's late effort.
Top display from Bramble, who was colossal at centre-back. Solid in the air, while he repeatedly showed the West Ham forwards who was boss with a series of strong, but perfectly-timed tackles.
Looked slightly rusty on his return from injury in the opening stages, but all things considered, could not have wished for an easier game to ease himself back into action.
At times the Beninese attacker was majestic, turning the West Ham back line inside out with his twisting, turning runs. Played a crucial role in the build-up to Sunderland's second, bursting forward on the break, before jinking through the visitors' defence as McClean hit home Sunderland's third.
Alert and always open for the ball, the young Irishman's display was promising, if he remains wasteful at times. Still, finished with aplomb from a tight angle to wrap up a great afternoon on Wearside.
Looked more comfortable at left-back then fellow midfielder Colback in the opposite defensive position. Solid in the tackle and in his distribution.
A lively showing from Johnson, who maybe would could have made more of an impact given the freedom of attack handed to Sunderland by their opponents. Still, finished neatly to double the lead.
Martin O'Neill will be buoyed by his display, with Vaughan more than reliable in possession and linking up play well throughout.
Heeded the home crowd's calls to shoot early in the first half and duly delivered with a fantastic opening goal. Defied the odds alongside Vaughan to dominate West Ham's midfield pairing of Diarra and Nolan.
Started shakily, particularly against the forays of Demel, but soon found his feet in defence. As the game progressed it was Colback putting pressure on his opposite number, and he was unlucky not to score, instead seeing his effort crash off the post.
May not have got his name on the scoresheet - only the offside flag prevented him from doing so - but proved a nuisance throughout, holding the ball up well and making space which allowed his team-mates to plough forward.
Could do very little for all three goals, even making a great save in the build-up to Sunderland's second, only to be let down by his defence's inability to clear the ball.
Struggled with Johnson down the flank, but little can be expected of an inexperience 18-year-old when so many of his elders fail to show leadership.
Displayed good attacking intent down the right-hand flank, but the same could be said of his defensive duties, with McClean often allowed too much space and time on the wing.
It must have been a frustrating afternoon for the centre-back, who too often was the only man on hand to shackle Sessegnon and Fletcher. His own reputation continues to be bolstered, however.
Showed strength in the air, but was truly woeful on the ground. Repeatedly given the run around by Sessegnon before hobbling off to be replaced by Tomkins later in the first half.
Very quiet display from the 31-year-old in contrast to his second West Ham debut last week.
Far too often Diarra was the only West Ham player to take stock and keep the ball, with his team-mates offering little option to release. However, he went AWOL at times, and his poor headed clearance teed up Larsson for his goal.
As expected, the former Newcastle captain was the focus of boos from the home crowd, and did little to silence them. Despite his obvious strength, lost too many midfield battles against the less-accomplished pairing of Larsson and Vaughan.
At times the former Wolves man was non-existent, completely failing to take advantage of the out-of-position Craig Gardner.
Had a great chance to draw level midway through the first half but completely failed to control the ball in the box. His attacking intent soon relented, and he was understandably substituted at half-time.
Bullied by Bramble and O'Shea. His lack of movement and aerial strength will no doubt see future chances in the starting line-up curtailed, particularly with the arrival of Marouane Chamakh and the soon-to-return Andy Carroll.
Came on in place of the injured Collins with 10 minutes of the first half remaining. Similarly struggled with Sessegnon.
Ricardo Vaz Té
Looked lively after his introduction, and at least proved problematic for Sunderland's defence.
Did very little to suggest his time in English football will improve at West Ham following the loan switch from Arsenal.
