Serena Williams out of Rio Olympics after losing to Ukrainian Elina Svitolina

 Are all the big stars losing at Rio so they can go home early because of Zika Virus? Defending champion Serena Williams is out of the 2016 Rio de Janeiro Olympics, after losing to 20th-ranked Ukrainian Elina Svitolina.

Williams lost to Svitolina 6-4, 6-3 in the third round, ending her bid to become the first tennis player to collect a pair of singles golds.

 Although she won gold medals in singles and doubles at the 2012 London Olympics, Williams heads home from Brazil with nothing as she and her older sister Venus also lost in the first round of doubles. Svitolina never before played in the Olympics and has only been to a major quarterfinal once.
