The answer to her second question? Less than three hours after play began.

When Nick Kyrgios became on Sunday the eighth man to withdraw, citing a persistent elbow injury, his line of the draw was left blank. Only one player, 182nd-ranked Mohamed Safwat, had signed in to be a lucky loser that day, and he had already been used as the seventh alternate when Viktor Troicki withdrew just before play began.

Any player who had lost in any of the three rounds of qualifying — and who had not entered the main draw of another tournament this week — would have been able to sign up and would immediately be placed in the draw, securing at least an additional 20,000 euros ($23,300) in prize money. There were 83 eligible players, but none had signed in at the referee’s desk before the 10:30 a.m. deadline on Sunday.

While most of those players had left town, many others were nearby, and simply unsuspecting of the opportunity. Thanasi Kokkinakis of Australia stayed in Paris after losing in the second round of qualifying and planned to practice near Roland Garros on Sunday. As a second-round loser in qualifying, he did not realize he was in contention to be an alternate.

“I had no idea how the rule works, so it’s probably my bad,” Kokkinakis said Monday. “I messaged the tour manager yesterday saying, ‘Would I have gotten in? And he said, ‘Yes.’”

Kokkinakis replied with a curse word.

Lucky losers have been a focus in tennis this year, when a new rule was implemented that offered injured players 50 percent of the first-round prize money at Grand Slam tournaments if they withdraw before their first match. Its purpose was to discourage players with pre-existing injuries from abandoning first-round matches.
