With Roger Federer already winning the group with a perfect record, Jack Sock and Sascha Zverev met in the second match of the day to fight for the second place that led to the Semi-Finals.
Zverev seemed nervous and often unbalanced, struggling for rhythm in the first set. He came to the set unprepared and was often passed. The American looked more cerebral and managed to hold his nerves to take the only break of the set. That proved enough to close the first set at 6-4 and the German frustration grew.
The fighting spirit of the Next Gen Superstar activated in the second set and started to overpower the Paris champion. He served big and calmly found the lines and built the points. Sock seemed overwhelmed as Zverev was in charge. He almost bageled his opponent, claiming the second set with a clear 6-1.
But his impressive form didn’t continue in the decider, as the American looked more focused, composed and decided. He was coming decisive to the net, taking time from the German. Alexander’s level went up and down during the set. When his serve crushed again, Sock was there to take full advantage. He advanced in the field and took the risk.
Zverev was too predictable in the decider and returned too short, as he opened the field for Sock.
Jack Sock barely qualified for the elite tournament, but now he makes a dream run to the Semi-Finals, winning 6-4, 1-6, 6-4. He will play next the revelation of the tournament, Bulgarian number 1, Grigor Dimitrov. The American holds a positive record against Dimitrov, 3-1, winning the last 3 encounters.
