Jannik Sinner overcame a mid-match wobble to see off the challenge of Germany’s Yannick Hanfmann in his Wimbledon opener on Monday but said he would have to raise his game. 

The Italian World No. 1 won 6-3, 6-4, 3-6, 6-3 in just under three hours on No. 1 Court to set up a match against 2021 Wimbledon finalist and compatriot Matteo Berrettini. “First-round matches are never easy and in the next round I have to raise my level,” said Sinner.
