The U.S. Open has been a very upsetting sports event this year – that is, in the fact that major upsets occurred all over the place. The men’s championship game, played tomorrow afternoon, features two players appearing in their first major final. And today’s women’s championship, while featuring the dominant and accomplished Serena Williams, has as the other finalist Caroline Wozniacki, who got here by outlasting Peng Shuai in a match, played under grueling, sweltering conditions, that ended with Shuai retiring, unable to continue, midway through the second set (pictured, with a concerned Wozniacki right there). So Wozniacki is tough, she and Serena are close friends – and this final ought to be quite interesting, no matter the outcome.
