Following his first full season on the ATP World Tour, Denis Shapovalov has withdrawn from the 2018 Next Gen ATP Finals due to exhaustion. After participating in the inaugural Next Gen ATP Finals last November, Shapovalov posted a 35-28 record across 18 countries in 2018 and achieved a new career-high 11 times in the ATP Rankings. The World No. 29 played eight events in seven countries over the final eight weeks of the regular season.

"I had a long year competing around the world and I'm sorry to pull out of the Next Gen ATP Finals," said Shapovalov. "It was a blast last year and unlike any other tournament I've ever played. I'll miss all of the amazing fans in Milan and battling against the best young players on tour."

In Shapovalov's absence, Hubert Hurkacz of Poland becomes the seventh direct qualifier for the 2018 Next Gen ATP Finals, which takes place 6-10 November at the Fiera Milano.
