World Records – Tennis
In our latest series we’re looking at world records set in different sports. Some were made to be broken, others may never passed, but all are equally impressive records.
Most Singles Titles
Throughout the history of tennis there have been lot’s of legends but nobody has one more than Jimmy Connors with a ATP World Tour-era leading tallies of 1,256 match wins and 109 titles. Rodger Federer is close behind at 99 career titles. 
The men are left in the dust by Martina Navratilova though. She has won 167 WTA singles titles, 58 more than Connors, and 99 more than current world No. 1 Serena Williams. Her career defines longevity and her record is could be hard to break in the modern age.

Most Grand Slam Titles
Men’s – Roger Federer has won 20 Grand Slam titles and still playing. He’s followed by the great Rafael Nadal with 17 titles. Women’s – Margaret Court has won 24 and is being trailed by Serena Williams with 23 Grand Slam wins and counting.
Oldest player to reach number 1
This is one world record in tennis that may be hard to ever beat. In February 2018 Roger Federer became the oldest male tennis player to be ranked No.1 in the world at 36. He surpassed the great Andre Agassi who was 33 years old when he was No.1 back in 2003.
Serena Williams is the oldest woman to ever reach number one spot. She was 35 when she traded the number one position back and forth with Angelique Kerber in 2017.
The most outstanding records in sport
The Fastest Serve
The serve speed of 263.4 km/h (163.7 mph) was recorded by Australian Sam Groth at an ATP Challenger event in Busan, South Korea in May 2012. However the Association of Tennis Professionals does not formally recognise service speed records made in Challenger tour events due to lack of uniformity in these tournaments’ radar guns! John Isner holds the ATP’s official record for the fastest serve at 253 km/h (157.2 mph).

The match lasted so long that it had to be spread over three days, and both players ended up with over 100 aces each. Isner has also been a part of the longest semi final in tennis history. His match with Kevin Anderson at Wimbledon 2018 lasted an incredible 6 hours and 36 minutes.
List of Wimbledon winners in the Open era
