Daniil Medvedev launched a new tirade against the Hawk-Eye technology used by ATP, this time at the 2025 China Open. The Russian's outburst came one year after he called out the ATP for the same issue in Beijing in 2024.On Sunday, Medvedev took on Alejandro Davidovich Fokina in the Round of 16 at the ATP 500 event. After a close call, the former World No. 1 wanted to see the moment replayed on the screen using Hawkeye, which was not available to be shown.Medvedev calmly shared his displeasure during the next changeover with the chair umpire, sarcastically asking why the ATP paid $10 million to use Hawk-Eye if it did not work as advertised."Aren't the ATP paying millions of dollars to Hawk-Eye, no?" Medvedev said to the umpire. "When you pay $10 million every year, you should just show it. It's OK."At the China Open last year, Daniil Medvedev was even more animated, calling Hawk-Eye "so bad" to use and telling the ATP not to buy the product anymore."The Hawk-Eye is so bad. Just show it!" he said during a clash with Carlos Alcaraz. "Why does the ATP pay for the Hawk-Eye if we can't see it? Don't buy the Hawk-Eye, guys. It's not my sponsor."Although he lost the match to Alvarez in Beijing, he avoided the same fate this year, beating Davidovich Fokina 6-3, 6-3 to book his spot in the quarterfinals.Daniil Medvedev to face Alexander Zverev in China Open quarterfinals next2025 US Open - Day 1 - Source: GettyFollowing his win over Alejandro Davidovich Fokina, Daniil Medvedev will take on Alexander Zverev in the quarterfinals of the 2025 China Open on Monday.
