STANFORD, CA, USA – Venus Williams’ serve has brought her plenty of wins and plenty of accolades down the years.

At the 2007 US Open, it also brought her a record, as she hit the fastest serve of all time. Williams’ delivery, clocked at 129mph, set a record that stood for seven years until it was bumped off top spot by Sabine Lisicki’s 131mph howitzer at Stanford’s Bank of the West Classic.

Williams herself is in action in Stanford this week. And while recapturing the title she won in 2000 and 2002 will be top of the agenda, recent form suggests that Lisicki’s mark could come under threat.

At Wimbledon, Williams enjoyed a welcome return to winning ways, reaching her first major semifinal since 2010 and putting the All England Club’s speed gun through its paces along the way…
