Roberta Vinci blocked Serena Williams from the Grand Slam with a win in what tournament?

Vinci had more losses in 2015 than Serena had that decade. Serena was on a 33-match Grand Slam winning streak...until she went to Queens, and got upset in the semis at the US Open. No one has gotten that close to winning the Slam in a calendar year without winning it.
