Sofia Open (Sofia, Bulgaria) - Preview

Jannik Sinner won his first ATP Tour title at the Sofia Open last November, and the 20-year-old Italian will try to retain his trophy this week at the ATP 250 in Bulgaria.

A tough field will try to stop the three-time tour-level champion, though. Gael Monfils, who made the semi-finals in Sofia two years ago, is the second seed. The Frenchman is also in good form after making the last four last week in Metz.

Other players to watch include third seed Alex de Minaur, fourth seed Alexander Bublik, #NextGenATP Italian Lorenzo Musetti and Winston-Salem champion Ilya Ivashka.
