Serena Williams' husband has said he "couldn't be more proud" of the Wimbledon runner-up after her remarkable performance at the All England Club. The 36-year-old American gave birth to daughter Olympia last September but complications including blood clots in her lungs put her life in danger. She needed surgery and was bed-bound for weeks, but Williams has managed to overcome those difficult days and resume her tennis career. In her fourth tournament back, just 10 months after becoming a mother, Williams fought her way through the Wimbledon field to reach the final. An eighth title was just out of reach, Angelique Kerber edging her out 6-3 6-3 on Saturday. Williams married businessman Alexis Ohanian in November, and he paid tribute to her achievements in London. He wrote on Instagram: "Days after our baby girl was born, I kissed my wife goodbye before surgery and neither of us knew if she would be coming back. "We just wanted her to survive-10 months later, she's in the #Wimbledon final. "Congratulations, @angie.kerber. "@serenawilliams will be holding a trophy again soon-she's got the greatest one waiting at home for her. Our family knows she'll win many more trophies, too. "She's just getting started. And I couldn't be more proud."
