New York: Tennis star Serena Williams beat Simona Halep, 6-2, 4-6, 6-3 on Wednesday to enter US Open 2016 semi finals. 
“I knew that I could play a lot better,” Williams said after her victory. 
“I felt like I kind of lost my rhythm a little bit in the second set, and also Simone started playing really well. I knew if I wanted to win this I had to step it up in the third set,” she added. 
The 34-year old tennis star is only two wins away from winning her 23rd career major and making history.  She is currently tied with Steffi Graf atop the list.
