The headline player is Alexander Zverev, 2018 Nitto ATP Finals champion and ranked No. 7 in the ATP Rankings. But the most crucial players on the German squad in Brisbane might be doubles stars Kevin Krawietz and Andreas Mies, the 2018 Roland Garros doubles champions who finished last year at the Nitto ATP Finals in London.
The much-improved Jan-Lennard Struff, No. 35 in the ATP Rankings, remains a tricky opponent for anyone as well.
