Wigan have swooped late on transfer deadline day to sign Conor Sammon from Kilmarnock.
The 24-year-old Irish striker put pen to paper on a three-and-a-half year deal just moment before the transfer window closed.
Sammon scored 24 goals in 64 apperances for Kilmarnock, and has 15 goals in 20 starts this season. Latics boss Roberto Martinez told the club's website: "Conor is a young, hungry player we have been looking at for a while.
"He has developed in an incredible manner over the last six months and it's fortunate that we've been able to move for him before he has achieved his full potential, which we're hoping he will do in a Latics shirt. We are delighted to welcome him on board."
Sammon won't be involved against West Brom on Tuesday night but he was delighted to make the move south.
He said: "It was a big decision to leave a club that has been so good for my career but I'm a Wigan Athletic player now and I want to prove to everyone here they've made the right choice, and proves myself in the Premier League."
Martinez declared himself satisfied with Wigan's business in the January window: "Our main priority was to finish January stronger than when the window started.
"We've achieved that by keeping our best performers, who attracted well deserved attention within the game and we've got real satisfaction to be able to retain the services of Tom Cleverley and Ali Al Habsi until the end of the season, which is a major positive for us.
"The return of James McCarthy, Franco Di Santo, Victor Moses, and Emmerson Boyce after long term abscences all feel like fresh signings into the squad. The fans can be proud and excited about the challenge ahead."
