Atlanta United advanced past Chattanooga FC in the US Open Cup with a commanding 3–1 victory on the road, dominating the encounter through superior shot volume and clinical finishing. The visitors, operating in a 4-3-3 shape, peppered Chattanooga's goal with 17 shots, of which six found the target, while the hosts managed only four attempts with two on target from their 4-2-3-1 formation. Fafa Picault opened the scoring for Atlanta, who controlled the tie through sustained attacking pressure despite Chattanooga's goalkeeper keeping the deficit manageable with a 50% save percentage. The home side's custodian conceded 1.0 post-shot expected goals above their actual goals conceded, indicating Chattanooga created minimal clear-cut opportunities in a defensive display that proved insufficient against the MLS side's efficiency. Atlanta's progression reflects their superior depth and attacking capability in cup competition.
