Teenage tennis sensation Maya Joint continues to fly the Australian flag in the US, powering her way into the third round of the Cincinnati Open.
The 19-year-old overcame a mid-match wobble to put paid to 18th-seeded Brazilian Beatriz Haddad Maia 6-4 4-6 6-4 on Saturday (local time).
Joint proved much more effective on her first serve, landing 70 per cent of her first delivery compared with just 55 per cent for the Brazilian.
