Kim Min-jung
In 2010, Lee competed in the 2010 Uber Cup as a member of the South Korean women's national team. There she led her team to its first Uber Cup trophy, winning all 4 doubles matches she competed in through the tourney. In the finals, she and her partner Kim Min-jung won against WR #1 Ma Jin and Wang Xiaoli, beating them 18–21, 21–12, 21–15. Although Lee and Kim were not regular partners and Lee Hyo-Jung stopped playing WD regularly in international games, Lee played exceptionally well, proving why she was the most successful player in the 2008 Olympics, winning both gold and silver medals. In June, Lee continued on playing women's doubles with Kim Min-jung, winning the Indonesia Open and the Chinese Taipei Grand Prix Gold, and finishing as a runner-up in the Singapore Open. While waiting for Lee Yong-dae to recover from his injury, she played mixed doubles with Shin Baek-cheol.
