On 4 April, Katsidis faced Jesús Chávez at the Frank Erwin Center in Austin, Texas. This was part of the "Lightweight Lightning" event, a lightweight eliminator tournament organised by Golden Boy Promotions. After an initially tentative start by Katsidis, he was soon able to pull ahead on the scorecards due to his characteristic onslaught of attack, which ultimately forced Chávez (who had sustained a bad cut on his forehead towards the end of round four) to quit in his corner before the start of the eighth round.
