Megan Shackleton started her Paralympic singles campaign with a 3-0 win against Ghaliah Alanazi from Saudi Arabia, silver medallist in the Al Watani Para Open earlier this year. After taking the first two sets 11-4 11-5 she had to show her fighting qualities in the third set before taking it 11-9 to give the ParalympicsGB team a perfect start to the singles events.

“I was looking forward to getting out there again after my doubles,” said Shackleton. “This is my first event ever playing straight knockout so I was a little bit nervous going into it but I was really proud of how I managed to commit to my game and start as I mean to go on. There were some tricky moments in the last set, but I held my nerve and I think that will help me going into the quarterfinal.”

She will now play the number one seed and former World and Paralympic champion Borislava Peric-Rankovic in the quarterfinal on Wednesday. The pair last met in the Slovenia Open in May when Shackleton came agonisingly close to a first win against the legendary Serbian, holding a match point in the fourth set before losing 11-8 in the fifth.

“That gives me good confidence going into the match,” she said. “I showed in Slovenia that I’m right up there with her and I think on the day I demonstrated that I could have maybe taken that match. Hopefully in a few days’ time that is the case. She’s a great player and I’m well aware that I’m going to have to bring a really good game to the table but I’m excited. It’s my first quarterfinal at a Paralympic Games and I’m feeling in good shape.

“I feel the expectation because I believe I can get through the quarterfinals. I’ve got a lot of respect for Peric and she’s a fantastic player so I know it will take a lot and I’ll have to bring my best game but I’m excited to get out there and fight for a medal.”
