“Always has an excuse” – Alexander Zverev ignites fan controversy after blaming his glucose sensor in Taylor Fritz loss at Halle


Following his French Open win, Alexander Zverev made an appearance at the 2026 Terra Wortmann Open in Halle, Germany. He reached the semifinal round before losing to American tennis player Taylor Fritz in three sets.

The loss marked his 10th defeat against Fritz. Following the faceoff, the Roland Garros champion, who has been living with diabetes, admitted to struggling due to a faulty sensor that gave him incorrect blood sugar readings during the match. The device showed incorrect higher readings, after which he kept drinking glucose drinks and consumed 300–350 grams of sugar, making him unwell.

“This has never happened to me before. The glucose sensor I use gave me an incorrect sugar reading,” Zverev said. “I’ve had to take between 300 and 350 grams of sugar. I felt horrible. I’ve been using this sensor since 2017 and I’ve never seen such a big error. It was giving me very high values, when in reality they were very low. If anyone reviews the match, they’ll see that I was drinking one glucose drink after another.”

However, his justifications did not land well with fans, one of whom highlighted his seventh consecutive loss against Fritz. The fan described Zverev’s statements as ‘worst sportsmanship.’

This is his 7th consecutive loss against Fritz, and he’s known to make excuses. Worst sportsmanship in the game today.

One of the fans criticized him for making excuses, writing:

“He has it in for grandson Fritz; something always happens to him when he faces him.”

@jmgmoron Lo tiene de nieto Fritz siempre le pasa algo cuándo lo enfrenta.

Another fan acknowledged the unfortunate incident, but slammed the German player’s habit of making excuses after his defeats.

“I’m not saying he’s lying, surely things are as he says. But what is certain is that you’re never going to see him lose in a normal way and congratulate the rival for being better. Incredibly, for every match he loses, he always has an excuse.”

@jmgmoron No digo que mienta, seguramente las cosas sean como él dice. Pero lo que es seguro es que nunca lo vas a ver perder de forma normal y felicitar al rival por ser mejor. Increíblemente, para cada partido que pierde, siempre tiene una excusa.

Here are a few more reactions:

“Today there was no way to blame the track, the temperature, the wind, the crowd. The diabetes sensor got the blame kkkk,” a fan wrote.

@jmgmoron Hoje não tinha como culpar o piso, a temperatura, o vento, a torcida Sobrou pro sensor de diabetes kkkk

@jmgmoron Funny, whenever Fritzy beats him theres a physical issue apparently. I have a name for it ‘bad loseritis’ a very severe case.

@jmgmoron Mister excusas a regresado

Although Alexander Zverev lost to Taylor Fritz, he admitted that he could have outwitted the American if things had gone his way. While he fired 11 aces, Fritz scored 19. The American won scored 85% points on his first serve against Zverev’s 83%. The German admitted that in the past duels, Fritz was better than him, but he was confident this time. However, things went south for him.

“The disappointment is there because I feel like my tennis was there, but for other reasons I couldn’t show it. The last few times I played against Taylor he was a better player than me, but today I felt like my level was there. I just wasn’t physically able to demonstrate it on the court.” (via puntodebreak.com}
