Sam into Mallorca quarters

Sam Stosur on Wednesday hit Lara Arruabarrena off the court to advance to the quarterfinals of the WTA Mallorca Open.

Stosur’s 6-3 6-4 win over the Spanish wildcard means the Australian will feature in the last eight at a grass-court tournament for the first time since Eastbourne in 2011.

Next up for the 34-year-old will be either qualifier Alison Riske – who stunned second seed Angelique Kerber in the first round – or Slovenia’s Polona Hercog.

Stosur played an exemplary grass-court match to dismiss Arruabarrena, serving strongly and attacking ceaselessly – including several serve-and-volley plays – to register victory in a crisp 84 minutes.

She won nearly 80 per cent of first-serve points (that percentage climbed to 86 in the second set) and faced just two break points during the match.

Her triumph was capped by seven aces and 25 winners to just 11 unforced errors.
