The 23-year-old Alexander Zverev is through to his 21st ATP final at home in Cologne, repeating the feat from a week ago. The German took down the young Italian Jannik Sinner 7-6, 6-3 in an hour and 48 minutes, trailing 4-1 in the opener and overcoming that deficit to seal the deal in straight sets.
Sinner defeated Zverev in the fourth round at Roland Garros but couldn't repeat that despite a promising start, suffering four breaks and stealing Zverev's serve thrice, not enough at least for a set. Jannik held at 15 in the first game when Alexander sprayed a forehand mistake, followed by a service winner from the German who got his name on the scoreboard.
A teenager held at 15 with a service winner in game three and converted the fourth break chance in the next one to open a 3-1 gap. Sinner produced another fine hold with a drop shot winner in game five, moving further in front and controlling the scoreboard against the top seed.
The German held after deuce to reduce the deficit to 4-2 and pulled the break back a few minutes later when the Italian sprayed a backhand error. Zverev fired a booming ace to level the score at 4-4 and earned three break chances on the return, converting the third after a double fault from Sinner to serve for the set.
Alexander lost focus in those moments, getting broken at 15 to keep the youngster in the set.
