Bouchard moves past ailing Kerber in Madrid

Eugenie Bouchard was able to follow up her shock victory over Maria Sharapova by outlasting Angelique Kerber at the Mutua Madrid Open on Wednesday.

The Canadian backed up her big upset win with a 6-3, 5-0 result over former World No 1 Kerber, who retired hurt after providing very little resistance during the second set.

Afterwards, Kerber cited a left thigh injury as the reason for her withdrawal, but it will hardly matter to Bouchard, who has now beaten two high class opponents in a row – a far cry from her recent struggles.

To be fair to Bouchard, she headed into the match with a 3-2 head-to-head lead against Kerber, and with two of those wins coming on clay, this was always going to be a potentially tricky challenge for the German.

Bouchard fired 19 winners and hit just 10 unforced errors in the victory, which sent her through to her first ever Premier Mandatory quarterfinal.

The first set was a topsy-turvy affair, as both players struggled to hold serve, but Bouchard kept coming back at her opponent, and ultimately won the set with four breaks to three.

With her injury presumably worsening as the match progressed, Kerber provided almost no resistance in the second set, and she eventually threw in the towel just minutes before Bouchard would no doubt have wrapped up the contest herself.

Next up for Bouchard is eighth seed Svetlana Kuznetsova, who won both of their previous contests in 2014.
