Playing her first Grand Slam semifinal, Roberta Vinci recorded a spectacular victory over world No.1 Serena Williams, pretty much the undefeatable queen of women's tennis, and destroyed her chance of adding the Calendar Slam to her bio.
Serena Williams won the last four Grand Slams, but she needed the 2015 US Open to complete a Calendar Slam for the first time in her career, which is one of the rare feats she's yet to achieve, but 32-year-old Vinci stunned the tennis world, stopped the unstoppable American, in New York, and after the match uncontrollably shook from excitement.
