Cilic loses in straight sets to Estrella at Barcelona Open

BARCELONA, Spain (AP) U.S. Open champion Marin Cilic was eliminated in the second round of the Barcelona Open on Wednesday, losing to Victor Estrella of the Dominican Republic 6-4, 6-4.

Also, Santiago Giraldo of Colombia beat Joao Sousa of Portugal 6-3, 3-6, 6-1, to reach a third-round meeting against top-seeded Kei Nishikori, setting up a rematch of last year's final won by the Japanese.

Estrella broke Cilic four times on the outdoor red clay, stealing his serve to go ahead 5-4 in the second set, and finishing off the ninth-ranked Croat by holding serve to love.

Estrella, who had won only one match in his last five tournaments, celebrated after placing a long forehand out of Cilic's reach on match point.

It was only Cilic's third tournament of the season after he rested to recover from a shoulder injury. As the fourth seed, he had a bye in the first round.

''I was not too happy with the way I played,'' Cilic said. ''I made a lot of unforced errors. I feel I still need several matches to get my form to a good stage.''

Estrella, ranked 53rd, last year became the first Dominican to finish a season in the top 100.

On court No. 1, Pablo Andujar of Spain roared back to oust 11th-seeded Leonardo Mayer of Argentina 2-6, 6-1, 6-2.
