Tennis star Andy Murray announced Friday he'll retire no later than Wimbledon this year. The 31-year-old Scottish player didn't want to retire, but he had "no idea when the pain was going to stop" from a 2016 hip injury, he said at a press conference ahead of the Australian Open. Murray made his decision while training in December, telling his team "I cannot keep doing this" after the injury caused him constant pain for "about 20 months" he said Friday. "I think I can get through this until Wimbledon" in July, Murray said, but added "I am also not certain I am able to do that." Murray won the U.S. Open in 2012 before earning two Olympic golds in men's singles and two wins at Wimbledon.
