Linda Fruhvirtova defeated Jil Teichmann 6–2, 3–6, 6–2 in the first round of the WTA 250 Charleston tournament on clay on 3 April 2023, pulling off an upset against the pre-match favourite. Teichmann, who carried odds of 1.55, was unable to maintain consistency across the three sets, surrendering the opening set decisively before briefly levelling the match in the second. Fruhvirtova, the outsider at 2.61, regained control in the decider to secure a commanding victory. The result represents a notable early-round scalp for the Czech player and suggests Fruhvirtova's clay-court form was sufficiently sharp to trouble a seeded opponent.
