The final regular week of the 2024 Hologic WTA Tour calendar was a busy one, featuring WTA 250 events in Hong Kong, Jiujiang and Merida, where three distinct champions rose to the occasion.

Diana Shnaider underlined her status in Hong Kong as one of the year's most improved players with her fourth trophy of 2024.

Viktorija Golubic ended her title drought in Jiujiang, capturing her first trophy in eight years with her signature one-handed backhand.

And in Merida, Zeynep Sonmez made some history for both herself and her country with her first title. The Turkish newcomer had the most significant milestone in this week’s PIF WTA Rankings, jumping 36 spots from No.127 to make her Top 100 debut at No.91. The 22-year-old has been on the rise all year. She qualified for Roland Garros to make her Grand Slam main-draw debut, secured her first tour-level win on the grass in Berlin and reached her first WTA quarterfinal in Monastir in September.

Champions Reel: How Zeynep Sonmez won Merida 2024

Sonmez follows in the footsteps of Cagla Buyukakcay (Istanbul 2016) as just the second Turkish player to become a WTA champion and reach the Top 100.

Shnaider also reaches a new career high, climbing two places from No.14 to No.12. The 20-year-old, who was ranked as low as No.108 in January, dropped just one set in Hong Kong.

Former No.35 Golubic had dropped to No.168 ahead of Jiujiang, having failed to win back-to-back tour-level matches since the Australian Open in January. However, the 32-year-old Swiss responded by winning her second WTA title -- and first since Lausanne 2016 -- to leap 63 places to No.105.

Sramkova makes Top 50 debut, Li returns to Top 100

All three runners-up also make noteworthy moves. Jiujiang finalist Rebecca Sramkova has enjoyed a remarkable fourth quarter of 2024, winning 17 out of 20 matches since the US Open. That includes a first tour final in Monastir, a first title at Hua Hin 2 and now a third final in her past five events.

The Slovak climbs 10 places to enter the Top 50 for the first time at No.43. She briefly broke the Top 100 for the first time in May, but in mid-September had fallen back to No.136.

Former No.44 Ann Li enjoyed a resurgence in Merida by reaching her third career WTA final -- and first since winning Tenerife 2021. The 24-year-old American jumps 18 places from No.111 to No.93, returning to the Top 100 for the first time since October 2022.

In Hong Kong, Katie Boulter reached her third final of the season and climbs six to a new career high of No.23.
