- Serena Williams stormed past Yaroslava Shvedova 6-2, 6-3 on Monday, her 308th Grand Slam match win taking her past Roger Federer for most in major tournament history and into the quarter-finals of the US Open. World number one Williams was never seriously challenged by the 52nd-ranked Kazakh as she stayed on track for a record-breaking seventh US Open crown and 23rd Grand Slam title. Williams will face Simona Halep for a place in the semi-finals after the Romanian fifth seed dispatched Spain's Carla Suarez Navarro 6-2, 7-5. "Wow, it's really exciting," Williams said of moving out of a tie with Federer for most Grand Slam match wins. "This is where it all started -- 308 sounds pretty good."
