World No. 4 Rafael Nadal has opted out of his Wimbledon semifinal match against Nick Kyrgios, which was scheduled to be played on Friday. Nadal's abdominal injury, which intensified during his quarterfinal clash against Taylor Fritz, forced him to make the decision on Thursday.It was a heartbreaking moment for Nadal, ending his hunt for a third Wimbledon title ended in the most unfortunate manner. His win-loss record in Grand Slams this year is 19-0. While many from the tennis world, including Kyrgios, wished Nadal a speedy recovery, World No. 225 Tennys Sandgren of America seemingly took a veiled dig at the Spaniard."I wonder if Rafa steps on the court against anyone other than Kygs," Tennys Sandgren tweeted.Tennys Sandgren@TennysSandgrenI wonder if rafa steps on the court against anyone other than kygs91988I wonder if rafa steps on the court against anyone other than kygsFans were quick to call out the American for his comments. Here are some of the reactions to Sandgren's tweet."What a ridiculous thing to say. Rafa doesn’t fear any player. But an abdominal tear will only get worse and he can’t serve properly so no chance against anyone.

However, as reports of his tests emerged, it was known to fans that the two-time Wimbledon champion had a seven millimeter tear in his abdomen. But Nadal still wanted to compete on Friday.After pondering the entire day, the Spaniard called for a press conference and announced his decision to withdraw from the tournament.“I have to pull out of the tournament. As everybody saw yesterday, I have been suffering from pain in the abdominal area. That’s confirmed. I have a tear in the muscle. It doesn’t make sense to play, injury will get worse,” Nadal said.This meant that Australia's 40th-ranked Kyrgios became the first men's finalist, who will be joined by either Novak Djokovic or Cameron Norrie to fight for the title on Sunday.
