Raducanu to 're-evaluate' after flat Australian Open exit
The Briton won a stunning US Open crown as a teenage qualifier in 2021 but has not clinched a tour title since and has struggled for consistency and fitness.
Her latest disappointment came with a sluggish 7-6 (7/3), 6-2 loss to Austria's Russia-born Anastasia Potapova at Melbourne Park.
The 28th seed Raducanu missed the chance to test herself against world number one Aryna Sabalenka in the third round.
Raducanu admitted that she never felt comfortable on court against the 55th-ranked Potapova, despite being ahead 5-3 in the first set.
