Leigh coach Adrian Lam declared himself proud of his side after they won 16-10 to condemn Huddersfield to a fifth straight defeat.
The result marked only a fourth Super League win of 2024 for the Leopards and they were forced to do it the hard way after having three players sin-binned.
Ed Chamberlain and Frankie Halton were shown yellow cards towards the end of the first half before Brad Dwyer followed suit in the closing stages of the game.
