World number three Alexander Zverev moved into the last 16 at the Halle Open on Wednesday with a straight sets win over American Marcos Giron.
The Tokyo Olympic gold medallist won 6-2, 6-1, breaking his 43rd-ranked opponent four times on the grass at the traditional Wimbledon warm-up event.
A two-time finalist at the Halle Open, Zverev's march was only halted by an incident in the stands, when an advertising board fell on to a spectator.
The German second seed was quick to react, handing an ice pack into the stands to help treat the injured man, who was applauded as he left the stadium.
"It was a great match from me," Zverev said, adding "I felt like I didn't let him play that well, which was important.
"A good start to the tournament and I'm looking forward to tomorrow."
All the love for a win at home ❤️@ATPHalle | #ATPHalle pic.twitter.com/tzo7CvZCuG
