Three Points

🎾 A surprise to both: Alexander Bublik took down Jack Draper in four sets on Monday, keeping the Brit from reaching the quarterfinals. Throughout the match, it became clear that a different Bublik was on the court — one who showed a level of seriousness and desire that had been absent for most of his career.

  • What he said: “Sometimes in life there is only one chance, and I had a feeling that was mine. I couldn’t let it slip. Standing here is the best moment of my life – period,” Bublik said, getting a bit choked up before adding a moment of levity. “Thank you guys, that was amazing. I’m standing here like I won the thing, but what can I say? I can’t cry here – come on, let me be in peace.”
  • And what he said: “I don’t think I’ve reached my best level this week. Then today just a couple of dips here and there, and he took advantage,” said Draper. “Usually when you play someone like Alexander, he’s quite up and down with his level, but he was completely locked in. He’s obviously been that way this week, and that’s why he's beaten de Minaur and top players...Yeah, it hurts a lot, but I just move on.”
  • Maybe not a total surprise: In the Court Theory Roland-Garros preview, we noted that in Draper’s outstanding clay season performances, he made his seemingly impossible strategy of simultaneously grinding and red-lining work in best-of-three and asked if he could do it in a best-of-five format. And, if he could do it, for how long would it be possible?
  • Next: Bublik faces Jannik Sinner in the quarterfinals on Wednesday.

🎾 Another emotional victory: Lois Boisson, the 22-year-old French player ranked outside the top 300 in the world, stunned Jessica Pegula 3-6, 6-4, 6-4 to earn a spot in the quarterfinals of Roland-Garros. It was an emotional win for Boisson, who was set to make her French Open debut last year but was kept out of the tournament with a knee injury that sidelined her for nine months.

  • What she said: “Playing on this court with this atmosphere was amazing,” Boisson told the crowd on Court Philippe-Chatrier. “I gave my all and in the end I won, which is just incredible. I hope I’m going to win it all.”
  • One big jump: With the win over Pegula, Boisson jumps up almost 250 spots to approximately 120 in the world when the new rankings come out, with a chance to grab some more points in the next round.
  • Next: Boisson faces Mirra Andreeva in the quarterfinals on Wednesday.

🎾 Kyrgios cuts grass: After pulling out of Roland-Garros doubles with Jordan Thompson at the last minute, Nick Kyrgios has ended his grass campaign before it began. On Tuesday, he said he would miss all of the grass season, including his big goal of playing Wimbledon, posting on social media, “I’ve hit a small setback in my recovery and unfortunately won’t make it back for grass season this year.”
