Zverev blames faulty diabetes sensor for Halle semifinal defeat to Fritz amid 40°C heat
Alexander Zverev's quest for a first grass-court title continues after a 6-7(4), 6-4, 7-5 defeat to Taylor Fritz in the Halle semifinals, a match the German blamed on a malfunctioning diabetes sensor that caused him to ingest excessive sugar.
On-court drama in extreme heat
Playing under temperatures approaching 40°C, Zverev started aggressively, breaking Fritz for a 2-1 lead. But his energy evaporated abruptly. Fritz reeled off 13 consecutive points to pull level at 3-3. At 3-4, deuce, Zverev left the court for an eight-minute medical timeout to have his back readjusted, raising fears of a retirement. He returned to claim the first-set tiebreak 7-4 amid roaring crowd support.
I had extreme problems with my sugar today.
The sensor that betrayed him
Zverev, a Type 1 diabetic since childhood, revealed after the match that his continuous glucose monitor malfunctioned for the first time in nine years. The device initially warned of high blood sugar while he felt low. A recheck confirmed hypoglycemia, leading him to inject far too much insulin and then consume around 350 grams of sugar in gel form during the opening 45 minutes. The overload left him feeling terrible and physically absent for stretches.
I have had this sensor for nine years, and it was the first time it misread so badly. I felt terrible. I kept fighting and gave everything, but I was physically not there at times.
Fritz stays clinical
Taylor Fritz, the world number nine, stayed error-free despite the oppressive conditions. He broke Zverev at 4-4 in the second set after a contentious point penalty for time violation eroded Zverev's serve, then sealed the set 6-4. After a mandated 10-minute heat break, Zverev fought gamely in the third but could not resist Fritz's late break, falling 7-5 in two hours and 39 minutes. The win extends Fritz's head-to-head streak over Zverev to seven matches.
It was crazy hot here, I probably felt better than he did.
A drought on grass continues
The defeat marks Zverev's fourth straight Halle semifinal exit; he has now played the event ten times without a title. His only grass-court final remains Halle 2016 (lost to Florian Mayer) and 2017 (lost to Roger Federer). With Wimbledon starting on 29 June, the world number three still searches for his first ATP trophy on grass.
All-American final
In the day's second semifinal, Frances Tiafoe thrashed German wildcard Daniel Altmaier 6-1, 6-3. Fritz will face Tiafoe in Sunday's final, guaranteeing an American champion in Halle.
