i really would like to know if seles serve at 6:5 in the first set tiebreak was really out. it looked like an ace, but was called out. maybe the most biggest line mistake in the history of women tennis.
both djokovic and tsitsipas played their best tennis in the first set, but djokovic then had a very bad service game when serving for the first set, and then was awful in the second set. but he started very well against a very well playing opponent.
