Former champion Simona Halep reached the Wimbledon fourth round on Saturday with a comfortable 6-4, 6-1 win over Poland's Magdalena Frech.

Halep, seeded 16, fired an impressive 24 winners past her 92nd-ranked opponent, who has never beaten a top-20 player.

"I have great memories here and having won the title here before helps my confidence."

The Romanian will next face either two-time champion Petra Kvitova or fourth-seeded Paula Badosa for a place in the quarter-finals.
