Hailey Baptiste's dramatic upset victory over world number one Aryna Sabalenka has boosted her ranking and confidence, yet former player John Isner sees her as a top 20 talent rather than a top 10 contender this year.
Baptiste defeated Sabalenka 2-6, 6-2, 7-6(6) in Madrid on April 28 after saving six match points. The win marked her first WTA 1000 semifinal and ended the Belarusian player's 15-match winning streak. It was also Baptiste's first victory over a top-five opponent.
