A hampered Emma Raducanu crashed out of the Australian Open with a defeat to Danka Kovinic in the second round on Thursday.
World number 98 Kovinic beat the US Open champion 6-4 4-6 6-3 on Margaret Court Arena to become the first player representing Montenegro to reach the third round of a grand slam.
Raducanu was troubled by a blister on her right hand and although the 17th seed showed her fighting spirit to take a topsy-turvy match the distance, she was unable to avoid an early exit.
It had all started so well for the 19-year-old Raducanu, but Kovinic won five games in a row from 3-0 down in the first set and although the Brit got back on serve at 5-4, she was fell behind after being broken for a fourth time.
Clearly restricted by her damaged hand, the favourite mixed up her approach intelligently with a measured sliced forehand and levelled the match courtesy of two breaks, an overcooked forehand from Kovinic ending the set.
Kovinic saved four break points early in the decider and broke when her opponent sent a backhand long, but the battling world number 18 hit straight back to get back on serve at 3-2.
However, a stroke of good fortune via the net cord gave Kovinic another break point, which she won with a brilliant lob and went on to serve out the match.
Kovinic will face two-time major winner Simona Halep or Beatriz Haddad Maia for a place in the fourth round at Melbourne Park, having struck 40 winners to Raducanu's 27 in the biggest win of her career.
