Andy Murray suffered a losing start to 2022 as he was beaten by world number 76 Facundo Bagnis in the first round of the Melbourne Summer Series.
The 34-year-old produced an error-strewn display as he lost 6-3 5-7 6-3 to the Argentine.
The Scot slammed his racket into his bench in frustration during the deciding set.
Bagnis broke Murray in the fifth game of the set before serving out to take the match.
Murray came into the tournament with confidence having reached the final of an exhibition event in Abu Dhabi in December, losing the decider to world number five Andrey Rublev.
