The ABN AMRO WTT Rotterdam is one of the bigger event the post-Australian Open on the ATP Tour, and Greek star
Stefanos Tsitsipas will be competing in both the singles and doubles event.
Seeded second in the singles event, the World No.6 will face Egor Gerasimov in his opening round match on Tuesday. However, he will also open his doubles campaign alongside brother Petro Tsitsipas, as the duo will battle last week's Singapore Open titlists Joran Vliegen and Sander Gille.
The 2019 Nitto ATP Finals champion stated he has made an agreement with his brother, in that they would play more doubles together in 2021.
“I wanted to start the new year in the most fresh and dynamic way,” said Tsitsipas, who partnered his brother at the ATP Cup and the Australian Open last month. “I want to play as much doubles as possible with my brother, Petros. It’s been a dream of mine, but I haven’t made it happen a lot.
"I want to take the opportunity to play with him in 250 and 500 events, a Grand Slam, as we did. It was my best memory of my stay in Australia. I am primarily focusing on my singles career, but I also want to help my brother and his performances. I would only do it for my brother, and no one else. I want to build a team with him, exclusively with him. I’m not planning on playing with anyone else.”
