The 5th seed Tamara Zidansek has stayed on the title course in Bogota following a commanding 6-2, 6-0 win over Sachia Vickery in precisely an hour. The Slovenian ruled the court on both serve and serve, saving both break points she faced and creating unreal 16 chances on the return, converting five to hold the strings of the match firmly in her hands.
Vickery was in all kind of troubles from the very first point, struggling to find the rhythm or impose her shots in the rallies, having to play against ten break points in the opener. Tamara broke her in games one and seven for a 6-2, wrapping up the second set in less than 25 minutes to seal the deal and march into the last eight.
The 11th seed Lara Arruabarrena defeated a qualifier Jasmine Paolini 7-6, 6-1 in just 77 minutes, trailing 5-2 in the opener before rattling off four straight games to move 6-5 ahead, earning a break at 15 in game nine when Paolini served for the set.
The Spaniard secured a tie break with one mini-break in the eighth point, gathering the momentum and never looking back after two breaks of serve in set number two that pushed her over the finish line. World no. 138 Astra Sharma ousted the 8th seed Magda Linette 6-4, 6-3 in an hour and 13 minutes, never facing a break point and creating four opportunities on the return.
The Aussie broke in the very first game of the match and that proved to be the decisive moment of the opening set, making five good holds for a 6-4. Playing better and better as the encounter progressed, stealing Linette's serve in games one and nine in set number two to race into the quarters, happy with the way she performed against the better-ranked rival.
A lucky loser Sara Errani took down a qualifier Bibiane Schoofs 6-2, 6-1 in 65 minutes despite serving at only 44%. After hitting 18 double faults in the first round, Sara took a different approach, delivering more than 30 underarm serves and saving five out of eight break points she faced.
Schoofs was nowhere near that pace, giving away no less than 70% of the points behind the initial shot and getting broken seven times to propel Sara into the quarters.
