American Serena Williams had few problems in conquering 15-year-old CiCi Bellis to make the Miami Open fourth round on Sunday.
It was a 14th consecutive win on the hardcourts of the ATP and WTA Miami Open for Williams as she cruised to a 6-1 6-1 victory over the junior world No 1.
Bellis made the headlines at last year's US Open when she became the youngest player to win a match at the tournament since 1996 after upsetting 12th-seeded Dominika Cibulkova and said on Friday how much she was looking forward to facing her mighty opponent.
But the teenage challenger was no match for the big game of 33-year-old Williams, a 19-time Grand Slam champion seeking a record eighth trophy at her home event.
Williams is competing in Miami for the 15th time since debuting as a teenager herself in 1998, a year before Bellis was born.
"If you break down her age and her ability and how well I think she handled the moment and how well she played, I think it was good," Williams said.
Williams will next face Russian Svetlana Kuznetsova, who overcame German 13th seed Angelique Kerber 6-3 3-6 6-3.

Third seed Simona Halep was a 6-4 7-5 winner over Camila Giorgi, but the 30th seed's Italian compatriots fared better.
In the day's later matches, huge-hitting Sabine Lisicki battled past Ana Ivanovic 7-6 (7-4) 7-5.
Fifteenth seed Flavia Pennetta defeated former world No 1 Victoria Azarenka 7-5 7-6 (8-6) and Sara Errani, seeded 11th, booked her spot in the last 16 after hitting back to oust Garbine Muguruza 4-6 6-4 6-1.
Switzerand's Belinda Bencic knocked out German qualifier Tatjana Maria 6-4 7-5.
