Day 8 fourth-round matches
Serena is trying to join Venus in the quarterfinals of a major for the 24th time. In 18 of the previous 23 majors in which they've both made the elite eight, one of them has won the title.
They've split two matches in majors, with both meetings coming last year. Goffin won at the Australian Open, Thiem at the French Open.
Konta might be the hottest player on tour in 2017, having strung together an 11-1 record heading into her fourth-round match.
Brady, 21, is the first American woman to ever reach the second week of the Australian Open as a qualifier.
Not only did Istomin stun Novak Djokovic in the second round here, but he is the only Uzbek player, male or female, to ever reach the second week of a major.
Raonic is 4-0 all time versus Bautista Agut, while the Spaniard has never made it past the fourth round of a major in six tries.
Two days ago, Karolina Pliskova rallied from 5-2 down in the third set to beat Jelena Ostapenko.
A win would give Nadal his 30th appearance in a Grand Slam quarterfinal.
