Determination: Wheelchair tennis player wins 468th in a row

It is surely one of the greatest winning streaks in all sports.

Wheelchair tennis player Esther Vergeer won her 468th singles match in a row, a streak that dates to 2003. The latest victory by the 31-year-old Dutchwoman was a 6-1, 6-0 decision over Thailand's Sakhorn Khanthasit in Tuesday's quarterfinals at the London Paralympics.

Vergeer has been No. 1 in the wheelchair tennis rankings for more than 13 years. Richard Krajicek, the 1996 Wimbledon champion, calls her "perhaps the most successful sportsperson of all time." ( Also read: Wounded US veteran inspires as ballboy at US Open )

It is widely believed that only Pakistani squash great Jahangir Khan has had a longer run of consecutive wins - 555. But that was across five years, from 1981 to 1986. Vergeer's run has taken more than nine years. She says the 555 mark is "not a motivation."
