World number one Iga Swiatek made a winning start at the Australian Open as she beat German Jule Niemeier in straight sets at Melbourne Park.
Three-time major winner Swiatek, who reached the semi-finals last year, won 6-4 7-5 on Rod Laver Arena.
The Polish 21-year-old will play Colombian Camila Osorio in round two.
There were also victories for third seed Jessica Pegula, sixth seed Maria Sakkari and seventh seed Coco Gauff – who will meet Britain’s Emma Raducanu.
Top seed Swiatek, 21, took advantage as Niemeier’s serve faltered for the first time to edge the first set.
The German responded with an early break of serve in set two but Swiatek avoided being taken the distance, winning four successive games to set up her meeting with Osario, who beat Hungarian Panna Udvardy 6-4 6-1.
American Pegula swept aside Romania’s Jaqueline Cristian 6-0 6-1 in 59 minutes. She will play Aliaksandra Sasnovich next following the Belarusian’s 7-5 6-2 win over 15-year-old Czech qualifier Brenda Fruhvirtova.
Sakkari progressed with a 6-1 6-4 win against China’s Yue Yuan and moves on to face 18-year-old Russian qualifier Diana Shnaider.

Last year’s American runner-up Danielle Collins, seeded 13th, needed three sets to defeat Russian Anna Kalinskaya, eventually winning 7-5 5-7 6-4.
Meanwhile, Wimbledon champion and 22nd seed Elena Rybakina said she “didn’t get the benefit which Grand Slam champions normally get” after being scheduled on an outside court for her first-round match.
“But I don’t really care and I just want to compete, I want to win. No matter which court I play on, it’s great to be here,” she said after beating Italian Elisabetta Cocciaretto 7-5 6-3…
