British ninth seed Cameron Norrie joined compatriot Heather Watson in securing a first Grand Slam fourth-round appearance with a straight-set win over American Steve Johnson.
He sealed victory in style as an ace closed out a faultless final set.
Norrie will next face another player from the United States, Tommy Paul, after the 30th seed beat Czech player Jiri Vesely 6-3 6-2 6-2.
World number 12 Norrie's victory came just hours after Watson defeated Kaja Juvan to also reach the last 16 of a Grand Slam in singles for the first time.
