Guillermo Garcia-Lopez dumped second seed Kevin Anderson out of the Estoril Open on Thursday to seal his place in the quarter-finals.

Robin Haase pulled off a shock win over top seed Feliciano Lopez on Wednesday and Anderson bowed out a day later when he was beaten 6-4 3-6 6-1.

The unseeded Garcia-Lopez had lost his only two games against the South African, but three years since their last meeting in was the Spaniard who prevailed.

Garcia-Lopez secured three breaks to Anderson's one and was clinical in the deciding set to seal his spot in the last eight.

Anderson battled to hold in the opening game of the match, saving a break point when trailing 30-40, but Garcia-Lopez was not to be denied the opening set as he claimed the solitary break in the fifth game.

World number 17 Anderson responded by going a break up to lead 3-1 in the second and then saved a further two break points before levelling the match, but it was Garcia-Lopez who came to the fore in the final set.

The 31-year-old reeled off five games in a row to stun Anderson, who had no answer to the rampant Spaniard, who may well face a tired Borna Coric in the next round after the Croatian teenager took almost two-and-a-half hours to see off Rui Machado 6-4 5-7 6-1.

Albert Montanes is another Spanish player through to the quarter-finals following his hard-fought victory over Gilles Muller.

The eighth seed was taken all the way to a final-set tie-break before sealing a 6-4 3-6 7-6 (9-7) win 

Pablo Carreno-Busta had earlier beaten fellow Spaniard David Vega-Hernandez 6-1 6-2 in only 61 minutes.

Vega-Hernandez took his place in the second round as a replacement for Tommy Robredo, who pulled out due to a foot injury, but was unable to make the most of his opportunity as he was comfortably beaten.
