Stoke have lost only one of their last eight Premier League games and the victory lifted them up to 10th place.
Hughes said: "It was a little bit difficult for us to get a foothold in the game in the first half. The wind was in our face and we didn't really get on the front foot and have that platform to build the performance.
"But I made a change at half-time and I think that probably helped us, and we were much better. We had the benefit of the wind at our back, which made an immediate impact.
"Obviously Charlie Adam) came on and scored, which settled the half very nicely for us, and we were very much on the front foot then.
"We had to pick ourselves up with the disappointment of the equaliser but I was really pleased with the reaction of Erik (Pieters) and his team-mates. They got round him, picked him up very quickly and that was important for us.
"And then we were able to go on and score a great goal at the other end. The second-half performance was very good."
