The US Open has come to an end. It was supposed to end earlier, but because of that heavy rain, it ended one day later. However, things did not go well. You know what I mean. Roger Federer lost in the finals.Juan Martin Del Potro beat him. It's disappointing. He actually did quite well in the semis but not as well in the final round. One shot that he hit(in the semis) was amazing. The ball went through between his legs yet he could return the ball swiftly.The way he did it was pretty cool.:)
