Steve Johnson had already gone through the emotional ringer at Roland Garros on Monday, when he won his first match at a major since the sudden passing of his father. "The last two weeks of tennis hasn’t been about tennis for me," the 27-year-old American said during a difficult press conference.

Johnson's emotions ran high again on Wednesday, when he faced Borna Coric. They were because of his great loss, of course, but also because of a controversial ruling by the chair umpire in the fourth set, with Johnson two points from winning the match.
