Heading into the clash at the Reebok Stadium, visiting Hull sat second in the Championship table and were regarded as the strong favourites to return to Humberside with all three points.
As it was, hosts Wanderers raced into a 3-0 lead within the opening 10 minutes, before going on to win the match 4-1.
Despite the success, Freedman has insisted that he will ensure that his squad do not get "too carried away".
"Our attitude was good, we created and took our chances and we were on the front foot for the majority of the game. It is a good result but we don't get too carried away," he told the club's official website.
"We continue to work hard in training and naturally it is pleasing when everything comes together like it did today."
The result has seen Freedman's team move up to 15th in the standings.
