Roberto Martinez praised his fringe players for seizing their chance as Wigan booked their place in the fourth round of the FA Cup with a 3-2 victory at Hull.
The Latics boss rested most of the players who had served him throughout the hectic festive period, with only Hendry Thomas, James McArthur and Maynor Figueroa keeping their places from the 1-1 Premier League draw with Bolton in midweek.
"We came here with a clear determination to be very professional," he said. "To give an opportunity to players that haven't been playing too much this season and I felt the way we applied ourselves was very professional."
He added: "We controlled the game from the beginning, probably we scored at the right times but every time we went forward, especially in the second half, we looked like we were going to score."
Until the final stages, things went very much to the script for Wigan, who took a two-goal lead through Mohamed Diame and a first for the club from 19-year-old striker Callum McManaman.
A late double from Hull veteran Nick Barmby kept the hosts in contention but Diame's second 13 minutes from time ensured it was the visitors who emerged victorious.
Wigan finished the match with four 19-year-olds on the pitch as Jordan Robinson, Jordan Mustoe and Daniel Redmond joined McManaman off the bench, and Martinez was thrilled to get such a positive glimpse of the club's future.
"It was pleasing for us in the last 10 minutes to be able to send on the youngsters to enjoy the moment and the experience of how to defend a lead, and I felt the whole exercise was a real success for us," the Spaniard added.
"It gives us a lot of new players who are going to help in the first team."
