With no national favorite Grigor Dimitrov, Stan Wawrinka was arguably the main attraction in Sofia this week but the 3-time champion was already eliminated this afternoon by 2018 finalist Marius Copil 3-6, 7-6(5), 6-4.
After having high hopes to start the year, Wawrinka is just 3-3 so far.
The field still includes a bunch of young stars who are all in the Top 20 and seeded 1-2-3: No. 1 Karen Khachanov, No. 2 seed Stefanos Tsitsipas and No. 3 Daniil Medvedev.
Trying to spoil the NextGen party are vets and former champion Roberto Bautista Agut, Fernando Verdasco and Gael Monfils.
Mirza Basic returns to defend his title.
Dimitrov, who won the title in 2017, decided not to enter the event.
