Michail Antonio scored for the third successive match at Upton Park as West Ham secured a 1-0 Premier League win over former boss Sam Allardyce and Sunderland.
Allardyce parted company with West Ham at the end of last season and once again defended his record at the club in the face of supporter criticism this week.
Successor Slaven Bilic has impressively steered West Ham towards the upper reaches of the Premier League – they move up to fifth on the back of this triumph - but there was little of the flowing football he is credited for introducing as an antidote to the Allardyce years in a drab affair.
Antonio's strike with half an hour played settled the issue, with the in-form winger needing little invitation to capitalise on a Patrick van Aanholt mistake.
There was a less accomplished piece of play from Mannone's opposite number two minutes later, when Adrian's ill-advised bout of kick-ups almost allowed Wahbi Khazri to open the scoring.
Khazri curled a free-kick on to the top of the bar following a further Adrian misjudgement but the Spaniard saw his team take a 30th-minute lead when Antonio skipped past Van Aanholt and steered a low shot into the far corner.
West Ham old-boy Jermain Defoe should have hauled Sunderland level within two minutes of the restart as he latched on to Lee Cattermole's lofted pass over James Collins but lashed wide left-footed.
Van Aanholt then fired wastefully over as Bilic's side continued their lethargic start to the second period.
Despite a number of promising set-piece opportunities, Adrian enjoyed a relatively untroubled second half until he made a timely block to deny Rodwell from DeAndre Yedlin's cutback.
West Ham substitute Andy Carroll volleyed against the crossbar but Allardyce was left to rue Rodwell's finishing once more, with the former Everton midfelder prodding over after a Byram mistake.
Dame N'Doye drew a sharp low save from Adrian in the 80th minute as Sunderland missed out on a point that would have lifted them out of the relegation zone.
