#NextGenATP star Jannik Sinner celebrated his 20th birthday in style on Monday as he overcome Argentine Federico Delbonis 6-2, 7-5 on his tournament debut at the Western & Southern Open in Cincinnati.
The Italian, currently at a career-high No. 15 in the FedEx ATP Rankings, played aggressively against Delbonis and rallied after losing three straight games from 4-2 in the second set to advance in one hour and 38 minutes.
Sinner captured his second tour-level title of the season at the Citi Open in Washington earlier this month to become the youngest ATP 500 champion since the category was created in 2009.

The 2019 Next Gen ATP Finals titlist was also victorious at the Great Ocean Road Open in Melbourne earlier this year. Sinner will next face either Toronto semi-finalist John Isner or Los Cabos champion Cameron Norrie in the second round.
In a lively start, Sinner fended off three break points, before quickly finding his range in his first meeting against Delbonis. The Italian struck the ball with consistent depth and was able to neutralise Delbonis’ topspin lefty forehand by taking the ball early at shoulder height.
After Sinner sealed the first set when Delbonis found the net with a forehand, the Italian quickly broke at the start of the second set. However, Sinner lost three straight games from 4-2 to trail 4-5 as Delbonis started to step inside the baseline and target Sinner’s backhand. The 20-year-old regained his focus though, breaking with a backhand winner before holding to seal his victory.
World No. 48 Delbonis, who was making his fourth appearance in Cincinnati, has enjoyed runs to the semi-finals in Hamburg, Belgrade and Santiago this season.
