The Swiss train is on its way!

Yesterday Jil Teichmann took care of Samsonova 6-4 6-4, validating exactly the angle identified before the match: Samsonova is structurally in trouble against left-handers, and Teichmann, with that left arm, imposes herself on clay, a surface that amplifies those differences in angles and spin. Born in Barcelona to a Spanish mother, she grew up on Catalan clay before representing Switzerland, and you can hear it in her tennis. Her sliced backhand, her topspin-slice variations, her ability to change depth and pace from the baseline make for a particularly rich tactical arsenal on this surface. Two WTA titles on clay in her career, SF in Rabat last week, 8-3 on WTA clay over the last 52 weeks. Her 2026 clay indicators back it up: Match Efficiency 1.159, Dominance Ratio 1.208, 45% of return games won, and 44.4% of points won on the opponent’s first serve.

Magdalena Frech got through yesterday against Ruse via retirement, 7-6 2-1, without playing a full match. The 27-year-old Pole, WTA No. 47, is 3-7 in her last ten matches and 3-5 on WTA clay over the last 52 weeks, i.e. 37.5%. Her WTA career record on clay at 40.4% wins confirms this is not her natural surface. Her flat baseline game, effective on hard courts, loses substance on slow clay that favors players able to vary spins and rhythms. Her 2026 clay indicators are below the break-even line: Match Efficiency 0.674, Dominance Ratio 0.741, only 30.8% of return games won. She comes in without rhythm after a cut-short match against a player coming off a straight-sets win.

H2H 1-0 Frech on grass in Birmingham in 2023, with no predictive value on clay.
