Kevin Anderson and Kei Nishikori, Lucas Pouille and Philipp Kohlschreiber, who are competing at the Erste Bank Open 500, visited the Vienna State Opera on Monday.

Austria’s opera house, which employs more than 1,000 people, produces 50 to 60 operas per year and 10 ballet productions, including more than 350 performances.

Home hope Dominic Thiem, who is currently eighth in the ATP Race To London for a spot at the season finale, to be held at The O2 in London from 11-18 November, leads the ATP World Tour 500 field in Vienna. Seventh-placed Anderson and 10th-positioned Nishikori are also in contention for the three remaining London singles berths.
