The most decorated wheelchair tennis athlete in the U.S., David Wagner has dominated the game in a way that few others have. He's competed at the World Team Cup every year since debuting at the 2002 championship in Lago di Garda, Italy, leading the U.S. to 10 titles.
A native of Portland, Ore., Wagner has won six Grand Slam singles titles and 18 doubles titles. He also has gold medals in doubles from the Athens, Beijing and London Paralympic Games, plus four silver and bronze medals in singles play from each of the past four Paralympics, held from 2004-16.
Wagner first became world No. 1 in October 2002, just three years after he started playing wheelchair tennis when he became a quadriplegic at age 21.
He suffered a spinal cord injury in 1995 after breaking his neck in an accident on the beach that left him paralyzed from the mid-chest down, retaining only 30 percent feeling in his hands. After he took up table tennis as part of his rehabilitation efforts, Wagner picked up a tennis racquet in 1999 and soon began to compete competitively.
