After spotting prominent red marks on tennis star Ben Shelton, US Open supporters took to social media and commented on the matter. The marks on his arms were visible to spectators as he defeated fellow American Francis Tiafoe in the quarterfinals on Wednesday.

The 20-year-old was competing in a sleeveless shirt under the spotlight at Arthur Ashe Stadium when his left shoulder and upper arm were encircled in little marks.

Many fans took to Twitter and responded with their views. One fan tweeted: “What are those circles on Ben Shelton’s l arm? A rash? On Ashe?.”

Another wrote: “He had those back in the November Champaign challenger 2022 but thighs.”

A third suggested: “Ben Shelton has been doing cupping on his shoulders and upper arms.”

One of the fans responded: “Oh, cupping’s still a thing? I remember loads of athletes had the marks around the 2016 Olympics but you don’t seem to see it as much now.”
