Li Xiaoxia
Four years after competing in her first Olympics, Dvorak qualified for her second Spanish team, as a 24-year-old, at the 2012 Summer Olympics in London, by receiving an allocation spot from the Final World Qualifying Tournament in Doha, Qatar. With a maximum of two quotas per nation in the singles tournament, Dvorak accepted the third spot, and thereby competed only in the women's team event, along with her fellow players Sara Ramírez and Shen Yanfei. Dvorak and her team lost the first round match to the formidable Chinese trio Li Xiaoxia, Guo Yue, and Ding Ning, with a unanimous set score of 0–3 (4–11, 7–11, 12–14).
