Alexander Zverev, Aslan Karatsev and Felix Auger-Aliassime will lead the field at the MercedesCup in Stuttgart. The ATP 250 is the first of seven grass-court events on this year's calendar, and it begins on 8 June.
Karatsev has been the breakout star of the season with a semi-final run as a qualifier at the Australian Open followed by an ATP 500 title at the Dubai Duty Free Tennis Championships.
Leaping from outside of the Top 100 in January to World No. 25 in the FedEx ATP Rankings, Karatsev has scored wins over the likes of Novak Djokovic, Daniil Medvedev and Andrey Rublev. Stuttgart will mark Karatsev’s tour-level grass debut.
The field includes Madrid champion Zverev, Rome semi-finalists Reilly Opelka and Lorenzo Sonego, new Top 20 member Jannik Sinner and three-time Grand Slam champion Stan Wawrinka.
Milos Raonic, who has not played since the Miami Open presented by Itau, is entered, with Auger-Aliassime and Denis Shapovalov also on the list.
