MIAMI (AFP) — After being harassed by a spectator during practice, world No. 2 Iga Swiatek beefed up her security ahead of her quarterfinal match against Alex Eala of the Philippines in the women’s singles event of the Miami Open.

The issue comes after British player Emma Raducanu was targeted by a stalker during last month’s Dubai Open.

Media reports said that Swiatek was verbally harassed by a spectator, who has a history of online attacks against the player, during practice on Sunday.

“Security is a top priority. We monitor the network to catch these types of issues. Constructive criticism is one thing, and threats, hate speech or even disturbance during training is another — this cannot be condoned,” a spokesperson for Swiatek told AFP.

“We reported the matter to the tournament organizer, as well as to the WTA, which reacted immediately and took additional precautions, such as additional security, for which we are very grateful.”

“Ensuring the safety of the players is crucial, they are the ones at the center of the event, and it is our job to protect them,” the spokesperson added.

A spokesperson for the Miami Open said: “We take the safety and security of all players and tournament attendees extremely seriously.”

“We constantly evaluate any potential threats and take every measure to respond appropriately. To ensure the effectiveness of these efforts, we do not disclose the details of our security operations.”

The WTA declined to comment on the matter, directing inquiries to the response from tournament organizers.
