ESTORIL, Portugal (AP) Fifth-seeded Guillermo Garcia-Lopez of Spain beat Stephane Robert of France 6-3, 7-6 (3) to advance to the quarterfinals of the clay court Estoril Open on Wednesday.
The 47th-ranked Spaniard will next face the winner of a late match between France's Benoit Paire and Kyle Edmund of Britain.
Sixth-seeded Borna Coric of Croatia also made it to the quarterfinals by beating Rogerio Dutra Silva of Brazil 6-3, 4-6, 6-1.
Coric's next opponent will be either second-seeded Nick Kyrgios or Inigo Cervantes.
Eighth-seeded Pablo Carreno Busta of Spain eased past countryman Fernando Verdasco 6-1, 6-3 to reach the second round.
Verdasco acknowledged his victory just 48 hours earlier over Lucas Pouille in the Nastase Tiriac Trophy final in Bucharest, Romania had left him ''a little tired from a week of tough matches.''
