British teenager Laura Robson progressed to the third round of the Australian Open girls' championship after beating 11th seed Yulia Putintseva in three sets today.
Robson, who reached the final at the tournament last year, defeated the 15-year-old Russian 6-2 3-6 6-2 in one hour an 40 minutes.
Robson will play Romania's Cristina Dinu in the next round tomorrow.
The 16-year-old will also play in the quarter-finals of the women's doubles on Wednesday alongside Australia's Sally Peers.
The pair only teamed on the eve of the tournament after Peers' original partner, Isabella Holland, withdrew due to injury.
They will play 15th seeds Agnieszka Radwanska and Maria Kirilenko on Wednesday.
Meanwhile, there was also success for Great Britain's number one boys player Oliver Golding, who came from a set down to beat Ireland's Sam Barry 7-6 (10/8) 6-3 6-4.
Golding will play Australian wildcard James Duckworth in the third round.
Robson said she did not expect her heavy workload to undermine her hopes in either competition.
"I don't see why not. I've worked really hard on my fitness," she said.
"I feel a lot stronger than a year ago. I've really worked hard cross-training. I generally feel better."
The 16-year-old has already pulled out of the girls' doubles alongside Heather Watson to ensure she is not too burdened by the programme and admitted she felt like she had let down her close friend.
"We all thought it was the right decision that it would be too much," she said.
"I didn't say it to her, I felt so bad so my coach did.
"It was his decision more than anyone else so I'm going to put the blame on him. I felt really bad for Heather."
