Muguruza, Raonic crash as roof shuts on US Open

French Open champion Garbine Muguruza and Wimbledon runner-up Milos Raonic crashed out of the US Open Wednesday as the $150 million roof on Arthur Ashe Stadium rolled smoothly into action for the first time. Third seeded Spaniard Muguruza, who has struggled in the aftermath of her Roland Garros breakthrough in June, slumped to a 7-5, 6-4 loss to Latvia's Anastasija Sevastova, the world number 48.
