Jan-Lennard Struff defeated Camilo Ugo Carabelli 6-4, 6-3, 6-3 in the first round of the US Open. Struff's serve and return proved decisive: he hit 14 aces, converted five break points and saved two of the three break points he faced.
Struff edged the opener by breaking in game 7 to go up 4-3 and held on for 6-4. The second set saw Struff break twice to lead 5-2, then respond immediately after Carabelli got one break back to seal it 6-3. An early break in game 2 of the third set put Struff in control, and he never looked back.
Carabelli's 13 double faults and 40% second-serve points won were a heavy burden. Struff, by contrast, won 12 of 13 service games and saved 66% of break points, while earning 40 return points to Carabelli's 21.
