The Australian-born British left-hander, ranked 249th in the world and coming off a loss at an event in California on Friday, tweeted that she and a friend were in the crowd when gunfire began. “I’m okay,” she tweeted. “We were right there.. sounded like fireworks at first then everyone started running.
