Madison Keys defeated Karolina Muchova 6-4, 7-5 in the R16 of the Berlin Tennis Open 2026.
Madison Keys, ranked #26, took down world #10 Karolina Muchova 6-4 7-5 on the strength of her second serve — 67% of those points won to Muchova's 40%, a 27-point swing that decided the afternoon.

It's Keys' second win in two meetings, and she didn't drop serve until that lone Muchova break late.
