Big credit to Katie here, thought the match was gone at 2-4, but she rolls off 4 games in a row to take it the distance and she will be serving first in the decider - the person serving first have gone on to take the first 2 sets.
Not getting ahead of myself, but Hibino has taken the first set against Doi in a match you can stream. That match 'may' have interest for Katie and possibly Hev further down the line. Hibino has just broken in the first game of the second set so is in a commanding position there.
It says 'injury break' on the site I'm following the scores on. Katie obviously has had her fair share of these, but the 4 games lost by the Italian perhaps suggests it might be her?
