Grigor Dimitrov advanced to the US Open quarterfinals for the first time since 2019 by defeating Andrey Rublev in a five-set thriller. Despite a strong start, Dimitrov faced a formidable comeback from Rublev, who won the third and fourth sets but ultimately faltered in the decisive fifth set. Rublev's frustrations were evident as he injured his hand by smashing his racket and required medical attention. Dimitrov's experience and composure under pressure were crucial, as he saved 13 out of 18 break points and won six straight points in the second-set tiebreaker. With Serena Williams cheering him on, Dimitrov will now face either Frances Tiafoe or Alexei Popyrin in the next round. Meanwhile, Alexander Zverev is set to face Brandon Nakashima in the fourth round, with Zverev being the favorite to win.
