LUXEMBOURG - No.2 seed Garbine Muguruza posted some impeccable service numbers in her straight sets win over Stefanie Voegele to move into the second round at the BGL BNP Paribas Luxembourg Open.

Muguruza took a wildcard into the tournament to play Luxembourg for the first time since 2012, seeking to end her 2018 season with a few more wins under her belt.

Up against Voegele - a player Muguruza has never dropped a set against - the Spaniard recorded one in style, dropping a mere five points in total on her serve in the 6-4, 6-4 victory.

The No.2 seed made the perfect start against Voegele, breaking early to open with a 1-0 lead, but then found herself having to fight off three break points in the next game. Muguruza held firm, and settled into the match to post a near-perfect serving performance.

Muguruza didn’t drop a single point on her serve as she claimed her next four service games to love. This put the pressure firmly on the Swiss’ shoulders, and she couldn’t make any inroads on the rock-solid Muguruza serve as she marched ahead to take the opening set.

A similar pattern emerged in the second set: Muguruza notched a break at 2-1 to claim an early break, and then backed it up by reeling off four consecutive service games to love to close out the match after an hour and 12 minutes.

Muguruza played solid, clean tennis in her straight sets win - apart from her impressive service numbers, Muguruza recorded 31 winners and only eight unforced errors, keeping her opponent contained to just 11 winners and 13 errors.

But Muguruza was almost untouchable on serve, firing off seven aces, and winning 91% of points behind her first serve and 80% on her second serve. As a result, she saved all three break points she faced.

Up next, Muguruza awaits the winner between Dayana Yastremska and lucky loser Varvara Lepchenko in the second round.
