RG '20 I think. Dropped only 25 games until 4R compared to 30 this RG.
Probably his most dominant 1st round — 4th round slam performance which is pretty wild at his age. When in this form, he often drops a set in the 4th round match but there was zero hope for Diego today.
Other times he’s gone the first 4 matches without dropping a set at a slam:
‘20 RG (lost in finals to Nadal)
’19 RG (lost in SFs to Thiem)
’17 Wimby (lost in QFs to Berdych p)
‘15 AO (won title)
’14 USO (lost SFs to Kei)
’14 AO (lost QFs to Stan)
‘13 USO (lost finals to Nadal)
‘13 Wimby (lost finals to Murray)
‘12 USO (lost finals to Murray)
‘11 USO (won title)
‘08 RG (lost SF to Nadal)
’08 AO (won title)
