Did anyone catch El Niño’s rare flash of frustration at the US Open practice courts? Cameras caught Carlos Alcaraz in a tense chat with his team after spotting the US Open crew filming him. Looks like even the coolest champs get rattled when their prep could be exposed! With his title defense on the line and a tricky first clash against Opelka, will this moment fire up Alcaraz or add pressure? Can’t wait to see how he responds on court! #Sports #Tennis #Alcaraz
