Kessler is learning to slide on clay..

McCartney Kessler, 26 years old, world No. 53, a gritty player who never lets go. Three WTA titles in her career, including Hobart and Nottingham in 2025, and a final in Austin this year against Pegula. Her tennis is aggressive, her fighting spirit is real — she’s come back from a set down several times this season. Against Kalieva in the first round, she lost the first set before turning the match around in two clean sets, managing break points perfectly: 80% conversion against only 20% saved on her side, a sign of solidity in key moments. But there’s one number that sticks out: on the WTA Tour, Kessler has zero wins and six losses on clay over her entire career, and zero out of five in the last 52 weeks. Her first round this week against Kalieva was therefore her first WTA win on clay, and she came into it as a heavy favorite.

Janice Tjen, 23 years old, is one of the most surprising revelations of the past two years. She climbed from No. 411 to No. 41 in the space of a single 2025 season that was historic for Indonesia, becoming the first player from her country to win a WTA title since 2002. Her career clay record is remarkable for a player at her stage of development: 13 wins for just one loss across her entire ITF and Challenger trajectory, a 94.7% win rate on the surface at lower levels. Her 2026 season, however, has been mixed: five wins and nine losses overall, and she hasn’t played a single match on clay this year. In Miami, she lost in three sets to Putintseva. Her reliability on clay is well documented, but her level against the WTA elite is still a real question mark.

Introductions done; now for the match-up: first meeting between the two players. The paradox of this match is striking: Kessler is the favorite despite a disastrous WTA clay record, facing a player who loves the surface and whose defensive style — solid from the baseline, effective in long rallies — is exactly what makes life difficult for players who don’t know how to build points on clay. Kessler will feel mentally at home on American green clay, and her fighting spirit could allow her to adapt, but we’re asking a player who had never won on clay at WTA level to do it against someone who feels completely at home on the surface.
