Tennis superstar Serena Williams has broken yet another record at the US Open 2016. She has racked up 308 Grand Slam singles victories, and has surpassed the record previously held by Roger Federer.

On Monday, Serena Williams booked her way into the quarterfinals of the US Open 2016 Championships. She did so through an easy 6-2, 6-3 victory over Yaroslava Shvedova of Kazakhstan. The match was concluded in just over an hour, with Serena cruising through to another world record.

Serena’s powerful serve allowed her to overpower her opponent and gain an easy victory. According to a play-by-play match report by Eurosport, her fastest serve went up to 126 mph.

According to the official US Open website, Serena Williams has achieved 308 match wins throughout her career. She has now surpassed Roger Federer, and is on track to raise the bar even more. Federer decided to sit out the US Open this year, and still has the potential to gain the record back from Serena if he enjoys a successful season next year. However, 2016 is Serena’s year.  

On her way to gaining 308 victories, Serena has achieved six Australian Open titles, three French Open titles, seven Wimbledon titles and another six at the US Open. To date, she has a total of 22 Grand Slam titles.

Serena is currently tied with tennis legend Steffi Graf, with a total of 22 Grand Slam Singles records. She narrowly lost out on a calendar Grand Slam last year, but she has proven that she still has the strength to keep pushing herself to greater heights. She could potentially end the week with 311 victories and her 7th US Open title.

Standing in her way to even more Grand Slam singles wins and her path to a 23rd Grand Slam title is fifth seed Simona Halep. The Romanian booked her clash against Serena after defeating Spain’s Carla Suarez Navarro 6-2, 75.
