Britain’s Johanna Konta will play American Sloane Stephens in the Italian Open second round after a straight-sets win over her compatriot Alison Riske.
Konta, 27, took fewer than 90 minutes to defeat Riske 6-4 6-1 in the first round in Rome.
The British number one beat 2017 US Open champion Stephens in Brisbane in January – their only previous meeting.
Serena Williams is also through to the second round after beating Sweden’s Rebecca Peterson 6-4 6-2.
The four-time Rome champion will face sister Venus, the 1999 champion, in the second round.
Venus beat Belgium’s Elise Mertens 7-5 3-6 7-6 (7-4).
Konta’s victory on Monday was her sixth clay court win of the year.
