The Aegon GB Pro-Series Sunderland got underway on Monday as eight female players made it through qualifying to reach the main draw.

Teenager Aleksandra Pitak caused the biggest upset of the day by beating the higher ranked Alice Gillan.

Pitak, who also beat Gillan at a similar event in Wirral last week, recovered from a break down in the first set to record a 6-3 6-0 victory.

“I think I played really well,” said Pitak, who will now meet seventh seed Maia Lumsden in the main draw on Tuesday.

“I was happy with the way I was serving, but I knew that Alice is a great player who always gives 100 per cent so it was never going to be straightforward.”

Pitak will be joined in the 32-place singles draw by her sister Katarzyna, who came through a tough two-setter to beat Nell Miller 7-6(3) 6-4.

Summer Yardley overcame Louise Holtum 7-6(5) 6-3, while Tanysha Dissanayake defeated Ellie Tsimbilakis 7-5 7-5.

Kira Reuter, Anna Popescu, Lauren Bishop and Lily Ghodrati also progressed to the main draw.

On Tuesday, top seed Laura-loana Andrei and Britain’s Fed Cup player Freya Christie will get their tournaments up and running.
