The match that’s one too many for Jil?

On Friday, Mirra Andreeva became the youngest player to reach the Roland-Garros round of 16 three years in a row since Martina Hingis between 1997 and 1999. She already has 32 wins this season, a personal record, including 18 on clay. Against Bouzkova in the third round, 6-4 6-2 in 1h35, she showed a steady rise in level but also visible frustration: three conversions out of eight break points and 25 unforced errors. On clay over the last 52 weeks, she has 22 wins and 4 losses, with a breakpoints prevail of 1.620 and a dominance efficiency of 1.272, confirming that she’s making good use of what she creates. Last year at Roland-Garros, she suffered a major lapse in the quarterfinals against Loïs Boisson. These fluctuations in level are well documented.

Jil Teichmann embodies one of the most unique stories of this fortnight. The 28-year-old Swiss left-hander, away from the tour for seven months to recharge, returned to training in January and to competition in April. Admitted into the main draw thanks to her protected ranking, she currently stands at No. 170 in the world. At Roland-Garros, she beat Samsonova in the first round, Frech in the second, then overturned world No. 10 Muchová in the third from a position of being down 5–1 in the second set, closing it out 6–1 7–5. On clay over the last 52 weeks at WTA level, she has 10 wins and 3 losses. Over her career on clay at WTA level, she has a 58.1% win rate, and against the top 10 in her career she is at 50%. She is a true clay-courter, and her protected ranking doesn’t reflect that. This is their first meeting.

The 2026 clay stats reveal a real but more moderate gap than expected. The dominance ratio is almost identical, 1.274 for Andreeva versus 1.230 for Teichmann, which means both players create roughly the same number of opportunities overall on this surface. The difference widens in conversion: breakpoints prevail 1.620 versus 1.123, dominance efficiency 1.272 versus 0.913. Andreeva holds up better under pressure on serve, 69% at 40-40 compared to 51% for Teichmann, and saves more break points, 60.3% versus 49.6%. On the other hand, Teichmann is surprising on return: 44.6% on the opponent’s first serve versus 40.2% for Andreeva, and 45.7% of return games won versus 41.5%. Her left-handed ball creates specific angles that right-handers on tour don’t see often, and on clay that will slow down on Sunday, her heavy topspin will be more effective than it would have been on the livelier surface of week one. If Teichmann comes into this match with the mindset she showed against Muchová, she can swing the key moments in her favor.
