Tomas Soucek's second-half goal ensured West Ham overcame a tough test in the Carabao Cup third round at Lincoln with a 1-0 victory.
This was nothing other than 'job done' for the Hammers as Soucek's 70th-minute strike from a corner booked their place in the next round.
Boss David Moyes made a host of changes to his side but Soucek was one of his Premier League starters who was involved and that proved vital while goalkeeper Lukasz Fabianski also made a number of good saves.
League One Lincoln, who were winners at Sheffield United in the last round, gave them a scare and should have led in the first half but they could not produce another upset.
