Tennis ATP Odds: Monday marked the opening of the Tiriac Open, an outdoor ATP 250 tournament in Bucharest, Romania. The ATP 250 event is back after a hiatus that began in 2016. As an ATP 250 event, this won’t draw in the top names as they just finished the Monte-Carlo Masters this past weekend. At the Tiriac, the top seeds are the likes of Francisco Cerundolo and Adrian Mannarino.
