Alexander Zverev has qualified for the ATP World Tour Finals for the first time.
The 20-year-old German will be the youngest player to compete at the season-ending tournament since Juan Martin del Potro in 2008, a year before it moved to Londons O2 Arena.
Zverev has enjoyed a superb season, winning two titles, including Masters tournaments in Rome and Montreal, and climbing to No4 in the rankings.
He joins Rafael Nadal and Roger Federer in booking his place at the event, which begins on November 12, leaving five spots still up for grabs.
Its obviously a great event, playing in the O2 Arena is something amazing for any player, Zverev said on atpworldtour.com.
