Britain's Laura Robson missed out on a second junior Grand Slam title by losing to Russian Ksenia Pervak in the girls' final at the Australian Open.
Third seed Pervak, 17, broke the 15-year-old Wimbledon junior champion six times on the way to a 6-3 6-1 victory.
Robson fought back from 3-0 down to trail 4-3 but then served two double faults in game nine to gift her opponent the opening set.
Pervak then romped through the second set to win in 74 minutes.
"I felt she was generally more consistent than me and that was a key factor in why she won today, but it's disappointing to lose," Robson told BBC Sport.
Pervak, who turns 18 in May, is almost three years older than Robson, who celebrated her 15th birthday 10 days ago. The Russian is also 154 in the senior world rankings, 360 places above the Briton.
I know I'm definitely going to keep playing the main junior events but involve more seniors into my schedule
Laura Robson
Saturday's final was played on the main Rod Laver Arena, which was Robson's second experience of a Grand Slam show court after she played the Wimbledon final on Court One last July.
"Rod Laver was amazing. There wasn't as many people as Wimbledon had but it's still a huge stadium," said Robson.
"And dealing with the conditions has been really, really difficult so I'm just happy to get through it.
"I had my little bag of jelly snakes and kept snacking on them to give myself energy."
As for the future, Robson expects to play more senior events this year having made her WTA debut last autumn.
"I know I'm definitely going to keep playing the main junior events but involve more seniors into my schedule, but at the moment I'm not sure what my schedule is," she said.
Having already been offered a wild card into this year's Wimbledon qualifying tournament, Robson is hopeful she may get the chance to play in the main draw.
"That would definitely be nice but that's up to the All England Club to see if they want to upgrade the qualies wildcard," she said.
The Australian Open boys' singles title was won by Indian 16-year-old Yuki Bhambri, who beat Germany's Alexandros-Ferdinandos Georgoudas 6-3 6-1.
