He's won six medals in three Paralympics Games, half of them gold.
On Monday, top-ranked wheelchair tennis star David Wagner trained in Mission Viejo.
Wagner wanted to test the court prior to the Wheelchair Doubles World Championships this November, when Mission Viejo is scheduled to become the first U.S. city to host the event.
"It was exciting to get a training session here at the Marguerite Tennis Pavilion before I head to the Australian Open on Saturday," he said. "It is great having the advantage of being able to train here."
Wagner has ranked in the top three wheelchair tennis players since 2004, when he competed in the Paralympic Games in Athens. Since then he's taken medals in Beijing (2008) and London (2012).
The International Tennis Federation (ITF) Master Series – Wheelchair Doubles World Championships will be held Nov. 7-11.
