Former British number one Raducanu, given a wildcard in her return to the Championships after last year’s injury troubles, struck the ball confidently and clinically in a 6-1 6-2 win, according to B BÇ Sports.
It is the first time she has reached the third round of a Grand Slam tournament since lifting the 2021 US Open title as an 18-year-old qualifer.
Raducanu’s impressive victory came a couple of hours after 22-year-old qualifier Kartal produced the biggest win of her career to beat France’s Clara Burel in three sets.
Kartal, ranked 298th in the world, won 6-3 5-7 6-3 to become the first home player to reach the Wimbledon third round this year.
She will face US Open champion Coco Gauff after the American’s 6-2 6-1 win over Anca Todoni.
