Emma Raducanu is out of the Auckland Classic after falling to a 6-7 (5-7) 7-6 (7-3) 6-1 defeat by second seed Elina Svitolina in the second round.
Svitolina won the second after another tie-break and, with Raducanu tiring, took the third in just 31 minutes.
Next up for Raducanu is the Australian Open, which begins on 14 January.
The 2021 US Open champion was playing with fairly heavy strapping on her right thigh but went toe to toe with the world number 25 before fading after an intense first two sets that each lasted more than an hour.
