HOUSTON, TX, USA - A pair of former Top 30 players will battle for the Oracle Challenger Series title in Texas on Sunday, after Peng Shuai and Lauren Davis won their semifinal matches on Saturday.

Peng, a former US Open semifinalist and a wildcard in Houston, defeated No.4 seed Jessica Pegula, 6-4, 6-3, while Davis, a qualifier, rallied from a set down to defeat No.7 seed and former junior Wimbledon winner Sofya Zhuk, 3-6, 6-3, 6-0.

Contesting her first tournament since Wimbledon, former World No.14 Peng has scored two straight sets wins in her last two matches over promising American teenager and former junior World No.1 Whitney Osuigwe and Pegula.

The 32-year-old Chinesewoman needed three-set comebacks to defeat Beatriz Haddad Maia and top seed Belinda Bencic in her first two matches, and will face a woman in former World No.26 Davis who has taken down two seeds in her path as well this week. 

After coming through qualifying, Davis took out No.9 seed Nicole Gibbs earlier in the week, as well as Slovakia's Kristina Kucova and Canadian Katerine Sebov. 

The American would take the lead on the Road to Indian Wells leaderboard should she win on Sunday, with the Oracle Challenger Series awarding a wildcard to the 2019 BNP Paribas Open to the American player who accumulates the most points from the series of events.

Despite falling in the singles semifinals, Pegula came away with the doubles title alongside Maegan Manasse, as they defeated Desirae Krawczyk and Giuliana Olmos in the final, 1-6, 6-4, 10-8.
