Two-time Wimbledon champion Petra Kvitova routed American teenager Louisa Chirico 6-0, 6-0 in the first round on Tuesday for her first victory at the Porsche Grand Prix in three years.
The fifth-seeded Kvitova stormed to the double bagel victory in 54 minutes in the first meeting with Chirico, a qualifier ranked 121st.
Chirico's best chance to get on the scoreboard came in the 10th game where she wasted five game points, two of them with double faults and another two when Kvitova shots fell unreachable off the net cord.
Kvitova saved the only break point against her in the next game and then wrapped up matters with a return winner in first match point.
The 26-year-old had lost her first match the past two years in Stuttgart where her best showing to date is a semi-final from 2012.
She is also waiting for her first title of the year, with a place in the Indian Wells quarter-finals her top result.
"It was quick. Actually, I didn’t expect that. No, I think two years in a row I lost in the first round here. It’s always the first match on the clay that is not really easy for me. So, I’m very glad how I handled it today," Kvitova said.
Kvitova hopes to raise her form with the help of new coach Frantisek Cermak, a former doubles player, after she ended a long-term partnership with David Kotyza following a second-round exit at the Australian Open.
"I don’t think that he wants to change anything. I just think that he wants to build what is inside which is like aggressive play and serving well and going forward," Kvitova said.
Only two of Kvitova's 17 career titles have come on the slow clay, at the Madrid Masters 2011 and 2015. Her best result at the top event on the dirt, the French Open, is a semi-final in 2012.
Other first-round matches later Tuesday include seventh seed Carla Suarez Navarro v French qualifier Oceane Dodin, and former French Open champion Ana Ivanovic v German qualifier Carina Witthoeft.
The four top seeds - Agnieszka Radwanska, title holder and Australian Open champ Angelique Kerber, Garbine Muguruza and Simona Halep - have first-round byes.
Kerber opens Wednesday against fellow German Annika Beck, who admitted she is "definitely the underdog" after beating Italian lucky loser Camila Giorgi 6-4, 6-2.
Halep also has a German opponent in qualifier Laura Siegemund who rallied from 5-2 down in the second set to oust Russia's Anastasia Pavlyuchenkova 6-0, 7-5.
"I found the accelerator again in the end," said Siegemund. "It was important to stay calm."
