Zarina Diyas

At the start of the year Diyas lost in the first round of the Australian Open. First-round losses followed in Dubai and 2019 BNP Paribas Open and failure to qualify for the 2019 Miami Open and the subsequent loss of ranking points saw her once again drop out of the top 100. However in May, Diyas won the eighth ITF singles title of her career at the Kangaroo Cup, which was enough to edge her back into the top 100.

Diyas was ranked well into the top 100 on the New Year's Day of 2018 (No. 66), thus automatically qualified into the main draw of a Grand Slam for the first time since 2016 Wimbledon Championships at the Australian Open, but she lost in the first round to Sorana Cîrstea in three sets. In March, Diyas reached the 4th round of a WTA Premier Mandatory event at the Miami Open, but had to retire while a set down in her match against Karolina Pliskova. In May she reached the quarterfinals of a WTA clay court event for the first time in her career at the Internationaux de Strasbourg, losing in straight sets to eventual champion Anastasia Pavlyuchenkova. Subsequently, she won her first round match at the French Open, losing in the second round to Naomi Osaka. Unfortunately, in her first round match against Sam Stosur at the Nottingham Open Diyas suffered a serious knee injury which saw her miss the entire grass season. She returned for the US Open, but lost in the first round to Karolina Pliskova. Diyas was also unsuccessful in defending her title at the Japan Open losing the quarterfinals to No. 1 seed Zhang Shuai.

In August, in her best result at the US Open to date, unseeded Diyas advanced to the women's singles third round where she lost in straight sets to 17th seed Ekaterina Makarova of Russia, earning $105,090.

Diyas suffered a wrist injury in round one of Wimbledon and underwent surgery. She did not play in any tournaments in 2016 after that. As a result, she fell out of top 100.

Diyas has won one WTA title at 2017 Japan Women's Open as well as eight singles titles on the ITF Women's Circuit. On 12 January 2015, she reached her best singles ranking of world No. 31. On 8 June 2015, she peaked at No. 89 in the doubles rankings.

2014 was Diyas' breakthrough season. She made her season debut in Hong Kong, reaching the final of a 25K tournament, losing in the final to Elizaveta Kulichkova of Russia. She then entered Australian Open qualifying, registering a hard-fought three-set win over Aleksandra Krunić in the first round. She then came from a set down to defeat Andreea Mitu and get to the finals, where she beat Canadian Stéphanie Dubois. This resulted in the first main-draw berth in her career, as well as her first Grand Slam entry. In the first round of the main draw, she proceeded to beat fellow qualifier Kateřina Siniaková. In the second round, she breezed past world No. 52 Marina Erakovic to book her place in the third round. Diyas' run was ended there; however, as she went down to world No. 11 Simona Halep in straight sets. Nevertheless, her two early round wins helped boost her ranking to a career-high No. 112. Following the Australian Open, Diyas lost qualifying matches in Pattaya City and Doha. She would bounce back quickly, though, as she then easily won a 50K event in Quanzhou.

Playing for Kazakhstan at the Fed Cup, Diyas has a win-loss record of 18–8 (April 2020).

2013 was successful for Diyas – she began the year ranked world No. 264 and would finish the year ranked more than 100 spots higher. She began the year contesting many ITF events with modest results, before recording a big win over Kristýna Plíšková in the first round of the Malaysian Open. Her only tournament win came in Makinohara, where she defeated talented Swiss junior Belinda Bencic to clinch victory. She then advanced to another final in Taipei, but lost to Paula Kania in straight sets. She competed in one more event before finishing the year ranked world No. 163.

She then traveled to the United States to compete in the Miami, qualifying for the main draw and getting past Alexandra Cadanțu before losing to Sloane Stephens in the second round. Although she failed to qualify for the Family Circle Cup, she played at the Malaysian Open and advanced to the quarterfinals – her first WTA quarterfinal since the 2010 Kremlin Cup.

Prior to Wimbledon, Diyas was defeated by lower-ranked players in two warm-up tournaments, losing to 129th-ranked Sachia Vickery in Nottingham and to 146th-ranked Johanna Konta in Eastbourne. Diyas, however, reached the round of 16 at Birmingham, by defeating Kateryna Bondarenko in straight sets and through the withdrawal of Victoria Azarenka. Diyas subsequently lost to 12th-ranked Czech Karolína Plíšková 2–6, 2–6.

Despite the slow start on grass that left her unseeded at the Wimbledon Championships, Diyas managed to advance to the fourth round for the second consecutive year. Diyas beat 24th seed Flavia Pennetta, qualifier Aliaksandra Sasnovich and 14th seed Andrea Petkovic. However, her stealthy run at Wimbledon was ended by the fourth seed Maria Sharapova, 6–4, 6–4.

Her hardcourt season, however, did not fare as well as her performance on grass. Diyas failed to win in all her pre-US Open tournaments. In Washington, Diyas had to retire against Lauren Davis after trailing 7–5, 2–1. She lost to lucky loser Julia Görges 6–2, 1–6, 5–7 in Toronto, to Venus Williams 6–7, 4–6 in Cincinnati and to Irina-Camelia Begu in New Haven 5–7, 7–5, 2–6 - all in the first round.

At the first round of the US Open, Diyas was defeated by Polona Hercog 6–2, 7–5. This meant that she failed to repeat her third-round appearance in the previous year.

Diyas' attempt to return from her injury started with a series of losses. She lost in the opening rounds of her first four tournaments of the season before scoring her first wins at Quanzhou, reaching quarterfinals and losing to Zheng Saisai 2–6, 0–6. She then won her first ITF title since June 2014 in a 25K tournament in Nanning. At Zhengzhou, she managed to reach quarterfinals before losing to the first seed Peng Shuai 3–6, 3–6. At Anning, she reached final but lost to Saisai again 5–7, 4–6. At Gifu she lost in the first round to Luksika Kumkhum. She then lost to another returning player Magdaléna Rybáriková twice, in Fukuoka and Surbiton. Diyas then failed to qualify for the main draw of French Open as she lost to Bethanie Mattek-Sands 4–6, 1–6, despite having defeated Sachia Vickery and Polona Hercog in the first two qualifying rounds.

At Wimbledon, Diyas was given a wild card to the main draw. She won her first two-round matches against Han Xinyun (6–3, 6–4) and Arina Rodionova (6–4, 7–6). She lost to another returning player, Petra Martic in the third round 6–7, 1–6.

At the Japan Open, Diyas won all her qualifying matches to reach the main draw. She went on to score victories against higher-ranked players such as local favourite Misaki Doi, top 30 player Zhang Shuai, compatriot Yulia Putintseva and defending champion Christina McHale to reach final. She eventually beat fellow qualifier Miyu Kato 6–2, 7–5 to win her first ever WTA title.

Only main-draw results in WTA Tour, Grand Slam tournaments, Fed Cup and Olympic Games are included in Win–Loss records.

At the start of 2012, Diyas was ranked No. 352. She made two quarterfinals and one semifinal. In June, she won her third title in Bukhara, not dropping a set the whole tournament. Later that year, she reached the final of a $25K event in Taipei. The next week, she participated in a new WTA 125 event, also in Taipei. She drew top seed Peng Shuai and defeated the world No. 40 in straight sets. She followed this up by dismantling Varatchaya Wongteanchai, losing just one game. She then lost in the quarterfinals to Kurumi Nara, which would mark her final quarterfinal of the season.

In 2011, Diyas reached the final at Kunming. She then reached the semifinals at Wenshan but did not reach another quarterfinal for the rest of the year.

In 2010, she continued to rise up the rankings. Following mixed results for the first half of the year, she reached the final at Rome, losing to Patricia Mayr-Achleitner. Diyas played two more quarterfinals and one semifinal before reaching the quarterfinals of the Premier-level Kremlin Cup in Moscow. She qualified into the main draw and defeated world No. 49 Gisela Dulko in the first round. She then achieved the biggest win of her career by defeating top seed and world No. 7 Jelena Janković in the second round. However, she lost easily to Maria Kirilenko in the next match.

She played one more grass-court event before entering Wimbledon. There, she got her first ever win by defeating Frenchwoman Kristina Mladenovic in a rain-delayed straight-sets match. She followed this up with three-set wins against 15th seed Carla Suárez Navarro and former world No. 2 and 2010 Wimbledon finalist Vera Zvonareva, before losing in straight sets to third seed Simona Halep in the fourth round.

In 2009, Diyas battled through qualifying and advanced to two quarterfinals in Gifu and Fukuoka. She won her second title beating second seed Katalin Marosi to win another $25K tournament in Stuttgart.

She ended her season playing three tournaments in Japan with modest results.
