Vienna Tournament

VIENNA – Alexander Zverev has moved into first place in the ATP world rankings, surpassing Jannik Sinner. The 29-year-old German defeated Tallon Griekspoor in the round of 16 of the ATP 500 tournament in Vienna, 6-4, 7-5 in about an hour and a half of play, thus mathematically moving to the top of the rankings as of Monday. Zverev and Sinner both have 9,450 points, but the German leaps into the lead thanks to his greater number of Grand Slam titles this season, with two trophies (Roland Garros and the US Open) to the Italian's one. Zverev thus becomes the thirtieth player in the history of the rankings…
