Emma Raducanu raced into the second round of the Miami Open with a dominant 6-2 6-1 victory over Sayaka Ishii.
The British number two won her first match since dealing with a stalker at the Dubai Open last month.
Raducanu started fast by claiming the opening two games before Ishii found her rhythm and levelled at 2-2.
But the Briton reeled off four successive games to take the first set 6-2.
The 2021 US Open champion continued her dominance in the second set, extending her streak of successive games won to nine as her Japanese opponent, ranked 188th in the world, struggled in the Florida sun.
Ishii avoided a whitewash in second set by holding serve in the sixth game, before Raducanu took her first match point opportunity to claim victory.
