Jazz Tangcay Artisans Editor A few weeks after Serena Williams played her last tennis match to move away from the sport, Roger Federer on Thursday announced he is also retiring. In a video posted on his social media, Federer, who has won 20 Grand Slam titles, said, ” Many of you know the past three years have presented me with challenges in the form of injuries and surgeries.” He continued: “I’ve worked hard to return to full competitive form. But I also know my body’s capacities and limits and its message to me lately has been clear. I’m 41-years-old. I’ve played more than 1500 matches over 24 years. It has treated me more generously than I’ve ever dreamt, and now I must recognize when it is time to end my competitive career.”
