Stan Wawrinka was dumped out of the Internazionali d’Italia by Lorenzo Musetti – the Italian teenager storming to a 6-0 7-6 (7-2) triumph.
Wawrinka endured a first-set ordeal against an opponent 17 years his junior, winning only seven points on his own serve as world number 249 Musetti converted three of four break points on offer.
The 2015 French Open champion then dropped serve once more in the opening game of the second set before finally getting on the board at 1-2 and breaking back to level things up at 3-3.
The 35-year-old was able to battle on to a tie-break but Musetti reeled off five straight points from 1-1 to pull clear decisively.
Remember the name: Lorenzo Musetti
