Roger Federer and Daniil Medvedev will lead the field at this year’s Noventi Open, a grass-court ATP 500 event to be held from 14-20 June. Four Top 10 players in the FedEx ATP Rankings have entered.

Federer is a 10-time titlist at the event, where he has tallied a 68-7 record and reached at least the semi-finals in his past 15 appearances. Medvedev, the World No. 2, will make his tournament debut.

Alexander Zverev will try to triumph on home soil as he makes his sixth appearance at the tournament. The 24-year-old made back-to-back championship matches in Halle in 2016 and 2017, losing against Florian Mayer and Federer, respectively.

Andrey Rublev is the fourth Top 10 player in the field, and he will compete in the main draw for the second time after reaching the 2017 quarter-finals. Other players to watch include Canadian star Felix Auger-Aliassime, Miami champion Hubert Hurkacz, Spaniard Roberto Bautista Agut and former World No. 4 Kei Nishikori.

A German has won four of the past 11 editions of the event. In addition to Zverev, home favourites Dominik Koepfer and Jan-Lennard Struff have also entered.
