Rafael Nadal has criticised US Open organisers after they waited three days before suspending Italian Fabio Fognini for verbally abusing a female umpire.
Fognini, 30, used insulting language to Louise Engzell during his first-round defeat by compatriot Stefano Travaglia.
But the world number 26 played twice in the doubles before the Grand Slam board defaulted him on Saturday, saying they had to wait for a translation.
"Three days for that? I don't think so," world number one Nadal said.
"He has been out winning two matches since then. It is not the ideal situation. It would be much better to do it immediately, not three days later."
Fognini apologised for his behaviour in a post on Twitter, saying: "I would apologise to you fans, [and] to the referee for what happened.
