Stefanos Tsitsipas is through to the last 16 of his second straight major tournament after stopping Filip Krajinovic in four sets on Saturday.
The sixth seed, an Australian Open semi-finalist in January, resumed his darkness-suspended match against the Serb at 5-5 in the third set before eventually running out a 7-5, 6-3, 6-7(5), 7-6(6) winner.
