Australia's Samantha Stosur is through to the second round of the Internationaux de Strasbourg after scoring a fine straight-sets win over American Jessica Pegula.
The 35-year-old former world No.4, who won her most recent WTA singles title in Strasbourg two years ago, prevailed 6-4, 6-1 in just over an hour as she continued her build-up to next week's French Open.
Australian qualifier Astra Sharma also banked a notable win, claiming the scalp of Chinese eighth seed Shuai Zhang 6-4, 6-1 to set up a clash with Puerto Rican Monica Puig.
Queenslander Stosur next faces Ukraine's 19-year-old Dayana Yastremska, who earlier beat French veteran Pauline Parmentier.
Sixth-seeded Yastremska, who beat former US Open champion Stosur at the Australian Open in January in straight sets, won 6-2, 6-4 to claim her first win on clay for the year.
Top seed and Australian No.1 Ashleigh Barty kicks off her tournament on Tuesday night (AEST) against Daria Gavrilova, as the two Aussies face off on clay for the second time in three weeks.
Earlier this month, Barty beat Gavrilola in the first round at the Madrid Open in straight sets.
Barty holds a 3-1 edge in their head-to-head record ahead of her final hit-out before arriving in Paris, where she is guaranteed a top-eight seeding for the first time.
Among the men in action, Australia's Jason Kubler is through to the second round of qualifying at the French Open but compatriot Thanasi Kokkinakis was forced to pull out of his match because of injury.
Former world junior No.1 Kubler, who is himself battling back from injury problems, posted a 6-4, 6-4 win over Indian 24th seed Ramkumar Ramanathan at Roland Garros on Monday, setting up a match-up with veteran Serbian Viktor Troicki.
Troicki, 33, who beat German Kevin Krawietz 6-4, 6-3, has reached the fourth round in Paris four times and is himself fighting back after a six-month break due to a back problem.
"I'm very happy because my expectation was almost a bit too high [in recent months] so I had to re-evaluate where I am and how much tennis I've been playing since the US Open," Australian No.10 Kubler, 26, told the Roland Garros website.
"I rolled my ankle at the US Open, then I've sort of had that lingering knee injury and that came back, so I haven't played too much tennis.
"It's funny because when I was younger – probably 16 to 23 – I just played all clay … I was saying to the coaches I've been hitting on clay for a couple of months now but it's only last week I started feeling good on it, so I've probably timed it pretty well."
As Kubler progressed, compatriot Kokkinakis – who made the Roland Garros third round as a teenager in 2015 – was forced to withdraw from his opener with Czech 19th seed Lukas Rosol.
Kokkinakis was replaced in the draw at short notice by Amir Weintraub, but the Israeli was swiftly dispatched by Rosol 6-3, 6-1.
Sydney's James Duckworth was forced to retire against sixth seed Sergiy Stakhovsky while trailing 4-2 in the first set.
And his 22-year-old countryman Marc Polmans battled well but suffered a 6-2, 1-6, 6-3 defeat in one hour 55 minutes to Italy's Gianluigi Quinzi.
French Open wildcard recipient Alexei Popyrin joined countrymen Alex de Minaur, Nick Kyrgios, John Millman, Matt Ebden, Jordan Thompson and Bernard Tomic in the men's main French Open draw last week.
But Thompson and Ebden's preparations were dealt a blow as they bowed out of the Geneva Open on Monday.
Thompson lost 5-7, 6-2, 6-4 to American Denis Kudla while seventh-seeded Ebden went down 6-2, 7-6 (7-4) to Nicolas Jarry of Chile.
Meanwhile, Tomic became another Australian injury victim when he was forced to quit his clash with Canadian Steven Diez in the ATP Lyon Open when trailing 6-4, 4-1.
