British number three Cameron Norrie is through to the second round of the BB&T Atlanta Open after beating Malek Jaziri on Tuesday.
Norrie, ranked 73 in the world, overcame Tunisia's 34-year-old world number 60 Jaziri 7-5 6-0 in Georgia.
Norrie battled back to claim the first set after going 5-3 down when his serve was broken for the second time.
The 22-year-old then had a far more comfortable time of it in the second set as he wrapped up the win in an hour and 15 minutes.
Norrie will now face sixth-seeded Frenchman Jeremy Chardy, who defeated Lithuania's Ricardas Berankis 6-4 6-3.
