Great Britain's Gordon Reid and Alfie Hewett lost out to Stephane Houdet and Nicolas Peifer in the final of the men's wheelchair doubles at the Australian Open.
The top seeds had been hoping to secure their third consecutive Grand Slam doubles title but an assured performance from their rivals forced them to settle for the runners-up slot in Melbourne.
"A lot of games came down to percentages," said Reid. "They played the bigger points better than us."
Hewett, 20, added: "We wanted to get out there and go for it. Maybe at times we went for it too soon."
Reid had also been hoping to claim back-to-back doubles titles in Melbourne after winning last year with Joachim Gerard, beating Hewett and his then partner Fernandez in the final.
The British duo both suffered early exits in the singles but Hewett will still replace Fernandez as world number one after the tournament because of the Argentine's quarter-final defeat.
Meanwhile, Britain's Andy Lapthorne has withdrawn from the tournament through injury after losing in the quads doubles final alongside partner David Wagner and to Australia's Heath Davidson in the opening round-robin encounter of his singles campaign.
