Vienna Open : Top Seed Djokovic Ousted In Vienna Open Quarters

World Number One Novak Djokovic crashed out of the Vienna Open in the quarter-finals, losing in straight sets to Lorenzo Sonego.

Djokovic, who had a 39-2 record this year, failed to convert a single break point in a 6-2 6-1 loss while Sonego broke the Serb five times for the biggest win of his career.

Sonego's first top-10 victory capped a dream week for the 25-year-old, who lost the final qualifier but entered the main draw as a lucky loser.

Djokovic said knowing that he had already secured the year-end number one spot in the rankings affected his performance and the 33-year-old, who will not be defending his Paris Masters Crown, is already looking forward to the season-ending ATP Finals.
