Kristina Mladenovic and Pablo Carreno Busta will reach the Top 20 for the first time with their appearances in the semifinals of the BNP Paribas Open at Indian Wells.
Mladenovic, who won her first singles title this season, doesn't want to stop there.
"I want to keep going, you know?” she said. “I want to keep working on things that have been working well, against top players, and I'm more focusing on giving myself opportunities to play [those] kind of big matches and big stages.
"Eventually, you know, the ranking is just the consequence of all the work you put on a daily basis. Eventually you're playing those great matches better and better, and give yourself a chance to win them. And then the ranking obviously follows."
The 23-year-old from France said her offseason training has led to improved fitness and consistency, and her development as a top doubles player has added more elements to her game. She pointed to her quarterfinal victory against Caroline Wozniacki, saying she took charge by serving and volleying during important points and using some slices and drop shots.
