Masarova vs. Siegemund Prediction at the Thailand Open – Friday, September 20

Masarova Earns First Career Win over Top 50 Opponent

Tereza Masarova notched the biggest win of her career on Thursday by upsetting the No. 6 seed Elena-Gabriela Ruse, 6-3, 6-4, in the Thailand Open first round. Masarova, who is ranked No. 127 in the world, advanced to the quarterfinals for the first time since reaching the last eight at the Birmingham Classic in June. She will now face Laura Siegemund in the quarterfinals.

Czech has shown momentum

This is the second consecutive tournament in which Masarova has defeated a top-50 opponent. In her previous outing, she took down No. 49 Rebecca Marino in the first round of US Open qualifying. Masarova has now won three of her last four matches against top-100 opponents and has improved her record to 3-3 against top-50 players this season. The 27-year-old Czech is enjoying a solid season, having reached the third round of Wimbledon and the quarterfinals of the Birmingham Classic and the Prague Open. Masarova's performance at the Thailand Open is another indication of her quality and suggests that she could make another deep run in a WTA tournament.

Siegemund Wins in 3-Set Marathon

Laura Siegemund, who reached the Thailand Open semifinals last year as a qualifier, needed 3 hours and 10 minutes to defeat China's Wang Xinyu 0-6, 6-3, 6-4 in the first round. Ranked No. 145 in the world, Wang Xinyu had won seven of her last eight matches but faded after a dominant first set.

German goes the distance

Siegemund, 35, is a two-time WTA champion and has reached a career-high ranking of No. 27 in the world. However, she has struggled for consistency in recent years and has not won a title since 2017. This win, her second of the season against a top-100 opponent, could provide Siegemund with the confidence boost she needs to continue her climb up the rankings and find more success.

Matchup

Masarova and Siegemund have never met on the WTA Tour before. Masarova is the higher-ranked player and has been in better form this season, but Siegemund is a more experienced player and has won two of her previous three matches against top-100 opponents. This is a tough match to call, but Masarova is the slight favorite to win.

Prediction: Masarova in 3 sets
