VIDEO: Anisimova rushes off court in strange retirement against Fernandez

Amanda Anisimova retired in the middle of her Indian Wells second round match against Leylah Fernandez after failing to convert four match points.

The 20-year-old, who beat wildcard Emma Navarro in straight sets to reach the second round, took the opening set 6-2 and was 40-0 and 5-4 up in the second before the US Open finalist came back to take the tie-break 7-0. With the match about to head to a third set decider, Anisimova walked up to the umpire to say she was retiring.

It was a strange way to retire from Anisimova who rushed off the court abruptly. The umpire said:

"Can you wait for supervisor because it's all of a sudden let's wait. Amanda please wait for the supervisor, thank you."

Anisimova was already walking off court before the umpire could contact the match supervisor. She then said to the radio:

"Amanda wants to retire, she says she's really sick please come to the court as soon as possible."

The American walked off court. The umpire turned to the Fernandez and said: "OK, Layla it's finished"

Anisimova posted an explanation on Twitter saying she was feeling very ill for a few days but elected to play. She had to stop because her health was in serious danger. The tweet has since been deleted.
