Arina Rodionova

Rodionova made her debut as a professional in 2004 at an ITF Women's Circuit event in Protvino, Russia. In 2005, she won a title in Minsk, followed by another win in Moscow the following year. In 2008, she finished as a runner-up in an ITF event in Istanbul. In 2009, Rodionova won two ITF titles in singles and eight in doubles.

In 2010, Rodionova defeated Jarmila Wolfe in the final of a $25k tournament in Burnie. In doubles, she advanced to the final of the WTA Tour-level Malaysian Open with her sister Anastasia. Although they defeated No. 1 seeds Alisa Kleybanova and Yan Zi along the way, the sisters lost the final match to Chan Yung-jan and Zheng Jie in close three sets.

At the Australian Open, Rodionova equalled her career-best showing at a Grand Slam tournament by qualifying for the main draw. She lost in the first round to fellow qualifier Anne Keothavong, 5–7, 4–6. She then won a $50k event in May in Prague, partnering Darya Kustova. She qualified for the Birmingham Classic, and won her first-round match against Virginie Razzano. She then notched the biggest win of her career by defeating No. 1 seed and world No. 16, Kaia Kanepi, in the second round. She lost to the 14th seed Magdaléna Rybáriková in the third round. At Wimbledon, Rodionova barely missed out on qualifying for the main draw by losing to Kristýna Plíšková, in three sets. She achieved very modest results through much of the rest of the year, losing in the first or second round of most tournaments she entered.

In 2012, Rodionova lost in the qualifying rounds of the Sydney International and the Australian Open. She then lost in the quarterfinals of the $25k Burnie International. She then competed in two more ITF events – losing in the second and first round, respectively. She picked up form in ITF Mildura, reaching the semifinals. Rodionova then competed in three more tournaments, losing in the second round of all three. She then failed to qualify for the Danish Open. Her best result of the year came at the WTA Tour clay-court event Morocco Open. She defeated Darija Jurak, Karolína Plíšková, and world No. 108, Mathilde Johansson, to qualify for the main draw. Each match lasted three sets. She took on Timea Bacsinszky in the first round, started well by winning the first set 6–2, but was forced to retire due a severe wrist injury she sustained while trailing 0–4 in the second set. She was also forced to withdraw from the doubles competition, where she and Anastasia were the No. 1 seeds. She missed a big part of the clay-court season to recover from the injury. Rodionova returned in July; she only made it past the first round in one of five ITF tournaments. However, she had a great result in Las Vegas where she reached the semifinals. Following three more early exits, she reached the final of a $25k event in Traralgon, and followed this up by winning her next tournament in Bendigo. She finished the year with two more early-round losses in Toyota and Dubai.

Following the 2024 Australian Open, she reached the top 105 in the rankings at world No. 101, 20 years after her professional debut. With a win over Yuan Yue in Hua Hin, Thailand, she reached No. 97 in the singles rankings, on 5 February 2024, becoming the oldest woman to make a top 100 debut at 34 years old. She went one step further to reach her second career quarterfinal defeating another Chinese player, Bai Zhuoxuan.

She qualified for the main draw of the 2024 US Open, but lost in the first round against Chinese Wang Xinyu in three sets.
