ATP Finals : Nadal Beaten By Zverev In ATP Finals Opener
World Number One Rafael Nadal made a disappointing start at the ATP Finals as he suffered a first career loss to Germany's reigning Champion Alexander Zverev, going down 6-2 6-4.
Zverev broke serve in the fifth game and again two games later when Nadal Blazed a Wild forehand wide.
The 33-year-old dropped his serve again at the start of the second set and with Zverev rock solid on his own delivery he never allowed the Spaniard a glimpse of an opportunity.
Meanwhile, Stefanos Tsitsipas beat Daniil Medvedev 7-6 6-4 in a high-quality battle of the debutants.
Tsitsipas earned a set point in the opening set tiebreak with a volley onto the sideline and converted when Medvedev netted a forehand.
Striking the ball with venom, the Swashbuckling Tsitsipas earned three break points at 3-3 in the second set but Medvedev responded with some gutsy tennis to hang on.
A Misjudgement by Medvedev at 4-4, leaving a ball that landed on the baseline, gave Tsitsipas another break point and this time he took his chance.
Tsitsipas, who won 39 of 44 points when he landed his first serve, claimed victory with a smash.
