Spanish second seed Rafael Nadal will meet Britain's Cameron Norrie in the Australian Open third round after both won their matches on Thursday.
Nadal's bid for an outright men's record 21st Grand Slam continued with a 6-1 6-4 6-2 win over American qualifier Michael Mmoh on Rod Laver Arena.
British number three Norrie eventually beat Russia's Roman Safiullin to reach the last 32 for the first time.
After a long rain delay, Norrie clinched a 3-6 7-5 6-3 7-6 (7-3) win.
Norrie looked tight as he failed to serve out a landmark victory at 6-5, but regained his composure to win a tense fourth-set tie-break and tee up a first career-meeting with Nadal.
