The Barnsley head coach made ten changes for the cup match which they won 2-1 thanks to goals by Victor Adeboyejo and substitute George Moncur.
Goalkeeper Jack Walton impressed in the absence of Adam Davies who will miss the Walsall game on Wales duty while Jared Bird made a case to replace Australian Kenny Dougall in midfield.
Stendel told the Chronicle: “Three or four players showed they can play in the league on Saturday which is good because we have players injured and on international duty.”
Barnsley are using the Checkatrade Tophy, in which they have two more group games, to give fringe players an opportunity. Stendel said: “At the moment, we think it is a good chance for all the players to play and show what they can do to get in the league team.”
Stendel was pleased after his team came from behind to beat the League Two Latics. He said: “It was a good perfromance. “We have a young, new team on the pitch with ten players who haven’t played much. We tried to play and we came back from behind to win. We deserved to win.
“The attitude was very good. We had cramp, little injuries, but we fought and won the game. The main point I was staisfied with was how we improved throughout the game. It was good for the confidence of those players so they know they can win games.”
