Sometimes, sport doesn't always stick to the script. Take yesterday for example, the 40th ranked and unseeded Italian wasn't meant to stand in the way of Serena Willliams' procession to a calendar grand slam.
Things went according to plan when Williams took the first set 6-2, but a remarkable performance from Vinci fought back and she took the match in a three set thriller. She will now be joined by compatriot Flavia Pennetta in the final.
Vinci's post-match interview was hilarious, and she delivering a wonderfully honest response to how did she believe that she could beat Serena Williams. The sports world needs more Vinci honesty.
