The two-time Olympic gold medalist (full name: Mary Abigail Wambach) was pulled over by Portland Police just after 11 p.m. after an officer saw drive through a red light. She then failed a field sobriety test and was arrested for Driving Under the Influence of Intoxicants (DUII) -- Alcohol.
She was handcuffed and brought to the Central Precinct in downtown Portland, where she failed a breath test and was booked into the Multnomah County Jail on DUII.
"Wambach was polite and cooperative throughout the investigation," the Sheriff's Office said in a statement.
Wambach, 35, later apologized to fans via Facebook.
"Last night I was arrested for DUII in Portland after dinner at a friend's house," she explained. "Those that know me, know that I have always demanded excellence from myself. I have let myself and others down."
"I take full responsibility for my actions. This is all on me," she continued. "I promise that I will do whatever it takes to ensure that my horrible mistake is never repeated. I am so sorry to my family, friends, fans and those that look to follow a better example."
Wambach was part of the U.S. Women's team that beat Japan 5-2 in the World Cup Finals last year. She announced plans to retire in October, three months after the epic match, and played her final game in December.
