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. The best result of the year came at a WTA tournament in Prague, where she advanced to the quarterfinals with straight-set wins over Kristina Mladenovic and Petra Kvitová. Diyas went on to lose to Iveta Benešová. In September, she played her first grand slam, losing to Chang Kai-chen of Taiwan in the first round of the US Open Women's Singles qualifying.

She then lost in the quarterfinals to Kurumi Nara, which would mark her final quarterfinal of the season.

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.

2014: Breakthrough and Top 50

2014 was Diyas' breakthrough season. She made her season debut in Hong Kong, reaching the final of an 25K ITF 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 ITF event in Quanzhou.

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.

Diyas then went to Europe but lost early in the first two tournaments contested. At the French Open warm-up event in Strasbourg; however, she returned to form with a win over world No. 22 Kirsten Flipkens in the first round. She followed it up by dispatching Ajla Tomljanović before having to retire in her quarterfinal match. Holding a world ranking of No. 86, Diyas was granted a spot in the main draw of the French Open, but got a tough draw and was knocked out by Petra Kvitová in the first round. At the ITF grass court tournament in Nottingham, she advanced to the final but was narrowly beaten by Kristýna Plíšková.

She played one more grass court event before entering Wimbledon. There, she got her first ever win at Wimbledon 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 3rd seed Simona Halep in the fourth round.

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 6-2, 6-2.

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, Diyas' stealthy run at Wimbledon was ended by the 4th seed Maria Sharapova, 6-4, 6-4.
