No.2 seed Carla Suarez Navarro secured her place in the second round of the Ladies Open in Biel with a straight-sets win over American Julia Boserup.

Spaniard Suarez Navarro, the one-time world number six, came through 6-1 6-2 and will play Italy's Camila Giorgi for a place in the quarter-finals.

However, No.5 five seed Laura Siegemund failed to progress as she lost her first-round match 6-2 4-6 7-6 (7-3) against Viktorija Golubic of Switzerland.

Already through to the last eight is unseeded Czech Kristyna Pliskova, who followed up her win over Roberta Vinci by beating Donna Vekic 6-1 6-2.

Pliskova will meet Annika Beck or qualifier Marketa Vondrousova for a semi-final spot.

Also securing their place in the third round were German seventh seed Julia Goerges, who defeated Oceane Dodin of France 6-4 6-3, and Belgian's Elise Mertens, along with Anett Kontaveit of Estonia.
