(Reuters) - Greek 20-year-old Stefanos Tsitsipas added another notch to a remarkable breakthrough season as he beat Latvia's Ernests Gulbis 6-4 6-4 to win the Stockholm Open and claim a maiden ATP title on Sunday.
Tsitsipas, who has rocketed up the rankings to 16th heading into Stockholm, made up for losing two finals this year by outplaying Gulbis in straight sets.
