Alexander Zverev was dumped out on Thursday in the ATP Halle second round, leaving only one seed in the deplenished field.
The No. 3 went down and out to Frenchman Ugo Humbert 7-6(4), 3-6, 6-3, with NO. 4 Russian Andrey Rublev now the only seed still in contention.
The event lost 10-time champion Roger Federer in a second-round shocker to Felix Auger-Aliassime and second seed Stefanos Tsitsipa withdrew from the event after his Roland Garros finals loss at the weekend.
Zverev played the final here in 2017 but his results have declined ever since.
The 24-year-old lost in just under two hours to Humbert, who struck 10 aces.
Zverev was puzzled in defeat: “I don’t particularly know what I could have done differently, to be honest.
“Ugo was serving incredibly well in the first set, we both barely won points on each other’s serve. In the third set, I think he found his rhythm from the baseline,” the Paris semi-finalist said.
“He was outplaying me. It is not a great result for me, but I don’t know what else I could have done.”
South African Lloyd Harris defeated qualifier Lukas Lacko 6-3, 7-6(8) in 87 minutes to reach a place in the last eight at the Wimbledon look-alike event in a northern German village setting.
The 51st-ranked Harris managed 11 aces to improve to 14-10 on the season; he next plays Nikoloz Basilashvili, a winner over Arthur Rinderknech 6-2, 7-5.
American Seb Korda, son of former Australian Open winner Petr, defeated Asia’s top player as he put out Kei Nishikori 2-6, 6-3, 7-5.
