On Wednesday at the ATP 500 event in Acapulco, Miomir Kecmanovic produced some of his best tennis to upset Alexander Zverev, the 2021 champion. Entering the match with an 0-11 record against top-5 opponents in the PIF ATP Rankings, Kecmanovic relied on confident backhand play and aggressive serving to secure the win. Zverev committed 17 unforced errors on his backhand, compared to Kecmanovic's six, allowing the underdog to open the court effectively.
"It feels amazing, especially because it's been a rough couple of years," Kecmanovic said. "So I'm happy that some things are going my way finally." He added, "I guess I was more aggressive when it mattered. I served a lot better than my usual standards... Obviously he's the big favourite, so I didn't have any pressure there, but you still have to play well when it matters."
The victory improves Kecmanovic's Lexus ATP Head2Head record against Zverev to 2-2. He will next face Terence Atmane in the quarter-finals, after the Frenchman defeated wild card Rafael Jodar 6-2, 4-6, 6-1.
