Seafood and tennis players continue to be a match made in heaven. Fish is a staple in the diet of many professional, including Stefanos Tsitsipas. The 20-year-old recently learned how to make sushi doughnuts at the Sydney Fish Market.

"It was really fun, I learned something new. I learned a new skill today," Tsitsipas said. "It was exciting to cook...and the experience was great. I didn't even know sushi doughnuts existed until this day."

It wasn't all culinary topics for Tsitsipas, as he also revealed his lofty goals for the 2019 season.

"My goals this year are to make the semifinal of a Grand Slam, get into the Top 10, and get into the ATP Finals by the end of the year," the world No. 15 said.

Tsitsipas was the top seed in Sydney but lost his second-round match to Andreas Seppi. He has already become the first Greek player to win an ATP title, winning in Stockholm last year before capturing the Next Gen ATP Finals crown. 

Tsitsipas, who has never won a main-draw match in Melbourne in two previous trips, will open his Australian Open campaign against world No. 52 Matteo Berrettini.
