The Washington Spirit's Kelley O'Hara headed home in extra time as they defeated the Chicago Red Stars 2-1 to win their first National Women's Soccer League (NWSL) championship in Louisville, Kentucky, on Saturday.

O'Hara latched onto a long pass from rookie Trinity Rodman to score her first goal of the season past Red Stars keeper Cassie Miller in front of 10,360 fans at Lynn Family Stadium.

The scrappy Red Stars created opportunities but were hampered by the absence of key players such as Kealia Watt, who was hurt in the semifinals, and Mallory Pugh, who went off injured at the end of the first half.
