Top seed Jelena Jankovic cruised into the last four of the Copa Colsanitas with a straight sets win over Romania’s Alexandra Cadantu in Bogota.
Jankovic, the only seed left standing in a competition that has had more than its share of upsets, yielded just three games as she claimed a regulation 6-2 6-1 success.
Her semi-final opponent will be Italy’s Karin Knapp, who took a 6-3 6-3 win over Spain’s Lara Arruabarrena-Vecino.
World number 198 Paula Ormaechea is also through after seeing off Maria-Teresa Torro-Flor 6-1 7-5.
Torro-Flor is ranked exactly 100 places above the Argentinean, but was repeatedly broken on the way to defeat.
Ormaechea meets Teliana Pereira of Brazil next after she coasted to a 6-1 6-2 victory over Mandy Minella.
