## Day 14 (September 11)

In remembrance of the September 11 attacks, the United States Tennis Association (USTA) and the US Open have, among other things, painted the digits "9/11/01" on Arthur Ashe Stadium two days in advance of Day 14's scheduled women's final. The players at the US Open have also been given a white US Open cap with the digits "9/11/01" in black block figures on the side of the cap. For the men's final originally scheduled for 11 September, the USTA had planned for the finalists to walk through a path lined by an honor guard of New York police officers, firefighters, and Port Authority police. The USTA also had planned for the men's final a moment of silence, a military flyover, and the unfurling of a court-sized U.S. flag at Arthur Ashe Stadium, and these events were remain as part of the women's final. Cyndi Lauper contributed by singing the national anthem at the Williams–Wozniacki semifinal match on September 10, and Queen Latifah did the same at the women's final, the Williams–Stosur match.
