Caroline Wozniacki defeated Sara Errani in the US Open women's quarterfinals in decisive fashion on Tuesday evening, losing only one game in the entire match. She completely dominated Errani, including breaking Errani's service game every single time. 

Wozniacki will face Shuai Peng in the semifinals. It's her first trip back to the semifinals at the US Open and any Grand Slam tournament since 2011 for the former world number one. She has never won a major title, and has only ever once made it to a Grand Slam final - in 2009 at the US Open.
