Raducanu began her season with victory over Russia's Ekaterina Alexandrova in the first round of the Australian Open but could not repeat the feat at the Qatar Open in Doha.
Emma Raducanu suffers longest losing run of career as struggles continue Ekaterina Alexandrova got revenge for her Australian Open defeat with a straight-sets win in Doha.
Like against Vondrousova earlier this week, Raducanu got off to a strong start, moving into a 3-1 lead, and had she taken any of three chances for a second break of serve things might have turned out differently.
But Alexandrova began to really find her range on her big groundstrokes and by the time Raducanu won another game she was already a break down in the second set.
Raducanu's mentor Jane O'Donoghue flew out to Doha to offer support but could not help the former US Open champion engineer a change in fortunes.
