A single moment of precision from Olivia Moultrie proved the difference as Portland Thorns secured a narrow 1-0 victory over Washington Spirit in their NWSL season opener at Audi Field. The Portland midfielder found the back of the net in the 52nd minute, breaking a tense deadlock in an affair dominated by fine margins. Despite controlling possession for much of the match, the home side struggled to test the Thorns' goalkeeper, managing only one shot on target from twelve attempts. The visitors, conversely, made their chances count, with Moultrie's decisive strike marking one of their three efforts on goal. This hard-fought win gives the Thorns an early advantage in the nascent NWSL season, leaving the Spirit to rue their inability to convert sustained pressure into goals.
