In brief
The Paraguayan fell 6-3, 7-5, 3-6, 2-6, 7-6 after nearly five hours on Court Suzanne Lenglen.
He told Clay magazine that a woman cannot handle a demanding crowd and needs 'a lot of strength' to officiate.
He alleged the French crowd's support was decisive and accused Kouame of stalling between points.
Social media users denounced the comments as misogynistic; tournament organisers were asked for comment.
The match
Adolfo Daniel Vallejo, the 22-year-old Paraguayan ranked 71st in the world, was eliminated by 17-year-old French wild-card entry Moïse Kouame in a five-set marathon on Court Suzanne Lenglen. The encounter lasted four hours and 56 minutes, with Kouame finally prevailing 6-3, 7-5, 3-6, 2-6, 7-6 after Vallejo let slip a 5-2 advantage in the fifth set. The French crowd roared its support for the home teenager throughout.
Vallejo’s attack on the umpire
In the aftermath, Vallejo singled out Brazilian chair umpire Ana Carvalho for what he perceived as her inability to manage the intense atmosphere.
“This sort of match needs to be umpired by a man, it's very difficult for a woman to do it. It has to be refereed by a man, because it's a very demanding crowd and you need a lot of strength to go against the crowd.”
Complaints about the crowd and opponent
Vallejo’s frustration extended to the behaviour of the partisan fans and what he described as time-wasting by Kouame. He claimed the crowd’s influence was decisive, stating:
“Did the crowd play a role? Yes. If we had played in another city, he would have lost 100%.”
“I think he took up a lot of time on many occasions, lying on the floor or stalling. And it’s not normal for the crowd to be shouting for a full minute without any play.”
Outcry and fallout
The sexist nature of Vallejo’s remarks drew swift condemnation on social media, with many pointing out that Carvalho is an experienced official. Tournament organisers at Roland-Garros were approached for comment. The incident has overshadowed what was otherwise one of the most gripping early-round matches of the tournament and adds a sour note to the fortnight in Paris.
