Hammers winger Matt Jarvis found the back of the net for the first time at the Boleyn Ground on Saturday after his cross eluded the Wigan defence and was allowed to drift into the far bottom corner of the net.
Despite both Mohamed Diame and Kevin Nolan attempting to make contact with the ball on the way past Latics keeper Joel, Jarvis' effort added a second goal to his West Ham tally.
"I was just pleased to see it go in at the far post," he told West Ham TV. "I was trying to get a good cross in and hope that if it does miss everyone, it goes in. I'm delighted with it.
"Generally that's the area you want to hit and luckily today it went in.
"I'm very pleased because to chip in with a goal is always nice and it's been something that I've really wanted to do.
"Wigan are a great passing team and we had to really dig deep today and show what a good defensive side we are.
"They were on top for long periods of the game but we took our chances and punished them, but we had to really work hard to keep the clean sheet. Our back four have excellent all season and today was no different."
Saturday's victory over Roberto Martinez's side sees the Hammers edge past the 40-point mark and Jarvis admitted the dressing room was buzzing.
"It's brilliant! It's one those when you come in at full time and the manager is delighted. All of the players are relieved we got the three points and now we can look ahead to the next fixture."
Nolan notched up his 100th career goal when his slick volley gave the claret and blue army a 2-0 advantage and Jarvis was quick to praise his the skipper.
He added: "Kevin [Nolan] is a fantastic player and a great leader and I am delighted for him to get his 100th career goal. It's very much deserved. We've all seen him finish like that many times before, he does it all of the time."
"I think we have shown all season what a good side we are, particularly at home and we can use our recent form to push us on in the remaining games of the season and get as high up the league as we can.
"It's a tough game to go next, away to Manchester City but we can take a lot from this and it's a great result."
