Jannik Sinner is delighting Italian fans for the second consecutive week after pulling double duty to lead Italy to a comeback victory over The Netherlands in their Davis Cup quarter-final in Malaga, Spain.

Fresh of his run to the title match at the Nitto ATP Finals in Turin, Sinner survived a tight opening set with Tallon Griekspoor before breaking open the match in the second to run out a confident 7-6(3), 6-1 winner to level the tie at 1-1.

He then partnered Lorenzo Sonego to a 6-3, 6-4 win over Griekspoor and Wesley Koolhof to book Italy’s semi-final spot against the winner of Thursday evening’s tie between Serbia, led by World No. 1 Novak Djokovic, and Great Britain.

Smiling into the semi-finals 😀

In his singles win against Griekspoor, Sinner leveraged his dramatically improved serve this year to drop just six points on his delivery, firing nine aces while also cracking 10 forehand winners.

Botic van de Zandschulp had earlier given The Netherlands a 1-0 lead when he saved two match points to defeat Matteo Arnaldi 6-7(6), 6-3, 7-6(7) in two hours, 52 minutes.
