PARIS, France – A brief delay truncated the order of play again on Day 2 of Roland Garros, but the first round got underway in earnest by afternoon; catch up with the biggest storylines as Tuesday’s matches came to a close. 

Aga and Simona roll, Muguruza survives: No one is talking about No.2 seed Agnieszka Radwanksa here in Paris, but she rolled through her opener against Bojana Jovanovski, losing just two games. She’ll have a much trickier task in the second round against Caroline Garcia, who played a sharp match to beat Lesia Tsurenko in straight sets.

Not be outdone on the day, Simona Halep matched Radwanska’s feat, losing two games to Nao Hibino. She plays Zarina Diyas next.

It was a different story for No.4 seed Garbiñe Muguruza, who needed three sets to get past a slumping Anna Karolina Schmiedlova 3-6, 6-3, 6-3. It was Schmiedlova’s 12th consecutive tour-level loss this year. Muguruza chalked up her slow start to, well, her headphones. The Spaniard didn’t hear her match announced over the loudpseaker and had just 10 minutes to warm up.

“I think I had the music on or something,” she said. “I didn’t really listen when someone talks with the speaker. The supervisor came, and they’re like, We’re waiting for you. I’m like, No way. I start to do running and jumping fast. So I didn’t have the time to really warm up.”

Cagla Buyukackay makes history: Buyukackay became the first Turkish woman in the Open Era to win a match at a Slam, as she rallied to beat Aliaksandra Sasnovich 5-7, 7-6(2), 6-2. You’ll hear more from Cagla on Tuesday.

Heather Watson streaks to a big win: Watson’s first round match against her doubles partner Nicole Gibbs was suspended on Sunday due to rain, with Gibbs serving up a break and a point away from consolidating at 2-1 in the third. On Monday’s resumption, Watson would save that game point and go on to win five straight games to win, 5-7, 6-2, 6-2.

“My first goal was to win that first point, because I knew it was very important. I could have been 3-1 down and just one point,” Watson said. “I actually had a talk with my coach and we talked for five minutes about how we’re going to play that first point. Once I got that, I think I just kind of settled. Especially once that game was done, I started swinging through.”

Currently ranked No.56, the win was a big one for Watson’s Olympic qualifying chances. She’ll play No.13 seed Svetlana Kuznetsova in the second round.

Roberta Vinci’s early exit: The highest seed to fall after the first two days in Paris: No.7 seed Roberta Vinci. The Italian has struggled with her form since the tour turned to clay, her most uncomfortable surface. She left Paris winning just four games against Kateryna Bondarenko.

Tsvetana Pironkova gets a win on clay: When you think of clay, you don’t usually think of Pironkova, a 2010 Wimbledon semifinalist. The Bulgarian, now ranked No.102, thrives on fast, low-bouncing surfaces such as grass and very particular hard courts – remember that Sydney title? – but clay has been a challenge.

On Monday she faced off against one of the best clay courters on tour in former Roland Garros finalist and No.16 seed Sara Errani. The Italian came into Paris struggling, having gone 0-3 on European clay this season, and the lack of form showed. Pironkova rolled to a 6-3, 6-2 upset and will face Johanna Larsson in the second round.

Naomi Osaka continues to impress: The 18-year-old made the third round in her Grand Slam debut in January at the Australian Open. Now she’s into the second round at her French Open debut, beating No.32 seed Jelena Ostapenko 6-4, 7-5. She’ll play Mirjana Lucic-Baroni next.

Osaka admits she’s not adept on the red clay yet, but her game may be perfectly suited for the surface. Like many who grew up playing on green clay, the European red stuff has been a shock. “I was like, Oh, my God,” Osaka said when asked about her first reaction to red clay. “Because last year I didn’t really play red clay. I didn’t play any clay, I think, so technically this year is my first time on red clay.

“Oh, God,” she said, smiling. “I don’t know what I was thinking because it’s completely different…. It’s kind of slow, and then I’m just like, Oh, hardcourt, please. But, I mean, I have to adjust, so I can’t complain about it all the time.”

“I don’t have like a hateful relationship with clay. I used to think I was the queen of grinding and then I was like, Oh, now I have to hit. People that hit powerful do well on clay. They do well on any surface.”

Class of 1997: The young class of 1997 on tour has been a promising one. Belinda Bencic has obviously set the standard of the 18-year-olds, but Jelena Ostapenko, Daria Kasatkina, and Ana Konjuh have also been eying a surge forward. Osaka says there’s no rivalry between the young women. Just sources of motivation.

“They’re kind of doing better than me right now, but I don’t know,” Osaka said. “I am trying to do my own thing and I’m sure they’re trying to do their own thing. We’re all going for different goals that are kind of the same because everyone wants to be No.1 and stuff. I mean, I don’t have any like [ill will] – nothing but love. Like no negative feelings or anything towards anybody.”

Shelby Rogers ‘bolts’ into the second round: Read more about Rogers’ big upset over No.17 seed Karolina Pliskova here.

Serena Williams, Angelique Kerber, and Victoria Azarenka ready for Tuesday: After two rain-addled days in Paris, the forecast looks positive for Tuesday, which means in an ideal world, the first round will conclude as scheduled. World No.1 Serena Williams gets underway against Magdalena Rybarikova, Kerber is on upset watch against Nuremberg champion Kiki Bertens, and Azarenka plays Karin Knapp.
