Leicestershire's Katie Boulter secured one of the biggest wins of her career as she eclipsed an opponent more than 400 places above her in the world rankings in the first round of the Aegon Nottingham Challenge.
Seventeen-year-old Boulter defeated world No.132 Veronica Cepede Royg in straight sets 6-3, 6-2 to move into the second round of the $50,000 tournament.
Boulter belied her senior WTA ranking of 564th to breeze past her Paraguayan opponent, furthering her credentials after her first senior singles competition win in Sharm El-Sheikh.
On Tuesday, in the first round of the women's doubles, Boulter, along with Mayo Hibi, lost to Cepede Royg and her partner Stephanie Vogt, but gained revenge in the singles competition.
The Woodhouse Eaves-born star, a wildcard entry for Nottingham, now faces Tunisian world No.167 Ons Jabeur for a place in the quarter-finals.
Victory over Cepede Royg followed Wednesday morning's announcement that Boulter had received a wildcard for Wimbledon's qualifying rounds, for which the draw is made on Sunday.
It will be Boulter's first inclusion in the senior draw of a Grand Slam. She has had success at junior level, where she is Britain's top prospect at 25th in the ITF's rankings, finishing runner-up in the girls' doubles at the Australian Open in January this year.
