BARCELONA, Spain (AFP) - Frustration mounted for former Roland Garros finalist Guillermo Coria here Tuesday as the fading Argentine crashed out of the Barcelona Open 5-7, 6-4, 6-4 to Teimuraz Gabashvili.

Coria, who led 4-2 in the final set, could not hold on against the number 138 Georgian-born Russian, losing his opening match in just over two hours with nine double-faults.

The former third in the world now stands a distant 811th and has made just three Tour appearances this season.

But the South American remained surprisingly resilient in defeat after losing one month ago in a Naples challenger 6-0, 4-6, 6-0.

"Today I went away satisfied, not like in Italy," said Coria.

"There I felt ashamed for the people who had paid money to see me play.

"I've tried with many psychologists, but they haven't found the answer," he said of his long-term slump.

"It has to come from inside myself.

"I must be more humble, to accept where I am in the game. Before, I didn't enjoy my tennis. But it's different now."

The 26-year-old lost his ranking for a period last autumn and has had a difficult job in recovering from 2007 shoulder surgery.

He joins Gaston Gaudio in fading away, with the Paris champion from four years ago now ranked 310 with one ATP match in 2008.

Two Spanish seeds reached the second round through retirements.

Number 10 Nicolas Almagro advanced when Serb Viktor Troicki quit after losing a 6-2 first set and 16th seed Feliciano Lopez needed only 5-2 before Argentine Jose Acasuso gave up.

Briton Andy Murray was due on court later to play a repeat of the Marseille final he won in February over Croatian and fellow wild card Mario Ancic.

Murray took an entry into Barcelona, where he trained as a junior, after losing to Novak Djokivic last week in Monte Carlo.
