Aug. 31 (UPI) -- Novak Djokovic cited issues with his fitness level after his first opening-round loss at a Grand Slam in over two decades at the 2026 U.S. Open.
The Serbian tennis star was seen vomiting and cramping throughout the 4-hour, 36-minute match Sunday in Flushing, N.Y. Meanwhile, 25-year-old foe Mariano Navonel rallied to upset his 39-year-old favored foe 7-6(5), 5-7, 4-6, 6-2, 6-1.
"It's something that I've been carrying, unfortunately, pretty much every match this year: vomiting, throwing up, a serious issue there," Djokovic told reporters. "Then my whole body starts to collapse, basically cramping and pain.
"Yeah, the back just gave up in the end, and shoulder, and I couldn't close it out."
