Roger Federer will face John Millman for the third time in his career. They are tied on 1-all in the head to head meetings record, as the Swiss defeated the Australian in a 2015 Brisbane three-set match and then Millman took a revenge in the last year's US Open.
Federer's achievements in Halle are just impressive: the Basel native will make his 17th appearance in the German event, he will seek his tenth title. Federer has won 63 matches out of 70 played, and he lost the last year's final to Borna Coric.
Just Coric will make his debut against Jaume Munar. The Croat already beat the Spaniard, who trains at the Rafa Nadal Academy, in the 2019 Monte Carlo Masters. That was a tough match for Coric, who only prevailed in three sets.
Without a doubt, this time the court conditions will be very different as the match will be played on grass. 2018 Halle was a historical achievement for the Zagreb native as he defeated Federer for the first time to win his maiden ATP 500 title.
The fresh Stuttgart winner Matteo Berrettini will play against Nikoloz Basilashvili. The Italian has delivered an impressive tennis last week as he won all the ten sets played in five matches. The 2015 finalist Andreas Seppi will face the local hero Mats Moraing.
Seppi is coming from the qualies. The all French clash between Benoit Paire and Jo-Wilfried Tsonga will take place, the winner faces Federer or Millman. The Belgian David Goffin, who lost in the quarter-finals last week in 's-Hertogenbosch, plays against Guido Pella.
