Juan Martin to miss Australian Open as he continues recovery from knee injury

Fifth-ranked Juan Martin del Potro will miss the Australian Open as he continues his recovery from a knee injury. "I hope you have a great 2019. Recovery is going great and I will tell you later where I will be making my comeback," the 30-year-old Argentine wrote on Twitter. "Unfortunately it won't happen in Australia ... but I'm happy with my progress." The U.S. Open finalist fractured his right kneecap after a fall at the Shanghai Masters in October. The Australian Open begins Jan. 14.
