Originally, Raisman tied with Russia's Aliya Mustafina for the bronze, until a tie breaker was induced and the bronze was awarded to Mustafina.
In the balance beam final, Raisman performed last. She originally scored a 14.966, but her coach, Mihai Brestyan filed an inquiry about her score.

On day one, she suffered an uncharacteristic fall on balance beam but rallied to finish the day strong, including posting the highest score on floor exercise of the night. She had a better competition on day two, choosing to remove some of her connections in her beam routine. She finished third in the all-around and won the title on floor exercise.
She was named to the American team for the World Championships in Glasgow, Scotland in October. There, she had some issues in qualifications, including a fall on uneven bars and rather low scores on balance beam and floor exercise.

She helped the Americans qualify first and qualified second to the all-around and floor exercise finals. She competed on three events in the team final, helping secure the gold for the Americans. In the all-around, she performed admirably, crying as soon as she finished her floor routines, overwhelmed with emotion, as she knew she had finally won an all-around medal: a silver. She won another silver on floor exercise.
