Serena Williams identified Roger Federer's one 'super underestimated' skill after playing him for the first time
- Roger Federer's serve is "super underestimated" according to Serena Williams.
- The tennis greats have a combined 43 Grand Slam titles between them.
- They played each other for the first time on Tuesday, with Federer coming out on top in a mixed doubles match at the Hopman Cup.
- Williams called his serve an "awesome weapon."
Roger Federer's serve is an "awesome weapon," according to Serena Williams.
Both tennis players, heralded as the best the sport has seen, made history on Tuesday when they shared a court in a mixed doubles match, with Federer and his partner Belinda Bencic prevailing over Williams and Frances Tiafoe at the Hopman Cup in Perth, Australia.
A 20-time Grand Slam champion, Federer has exceptional tennis intelligence, an outrageous forehand, and is a big-game player for the big occasions. But after playing against him for the first time in her career, Williams - who has won 23 majors herself - says he also has a "killer serve."
Aside from a rogue double fault, Federer served reasonably well during the January 1 dream match and scored winners against Williams.
In a post-match interview at the Hopman Cup, Williams said: "I think his serve is super underestimated… he has a killer serve, you can't read it, and there's a reason why he's the greatest as you can't be that great and not have such an awesome weapon like that serve."
Federer's fastest recorded serve speed is 230 kmh (143 mph) and has an average speed of 207 to 209 kmh (128.5 to 130 mph), according to the Sydney Morning Herald. He has 10,818 career aces in singles competition.
