Portland’s 2-1 victory in San Diego on Saturday night deepened a crisis that now defines the expansion side’s debut season. Five consecutive defeats have exposed structural frailties in San Diego’s defense — the Timbers’ winner arrived late, but the pattern was familiar: a momentary lapse punished by a more organized opponent. For Portland, the result provides a valuable road win in a Western Conference where road points remain scarce. For San Diego, the loss raises uncomfortable questions about whether the squad’s initial tactical coherence has eroded under mounting pressure. The club has not held a lead in any of the five losses, a statistical marker that suggests an inability to seize or protect momentum. The schedule offers no respite: San Diego next faces two sides above the playoff line, meaning the slide could deepen before any corrective action takes hold.
