First day of WTA 500 Adelaide 2 tournament brought great match-ups between the top players. The action on Centre Count was started by a hit clash between Petra Kvitova and Elena Rybakina. Kazakh, who managed to win one match in previous week's tournament at same venue had no response for a great performance of Kvitova, who won that match in 2 sets: 6-3 7-5.

This match was followed by the contest between Danielle Collins and Karolina Pliskova. The American who lost to Rybakina in R1 last week despite some good performance, showed a stunning performance today, hitting 27 winners in quick two sets, playing really aggressive tennis and using all the weaknesses of her opponent. Collins looked like she could sort out her vulnerabilities with service consistency, which stopped to unleash her full potential in recent months. Pliskova, who is stlil to find her form after realy week end of last season, did not capitalize on her two wins in weekend's qualies and had no response for a game of Collins, who can be one of the favorites ahead of next week's Australian Open after today's 6-2 6-4 win.. Danielle will face Jil Teichmann in R16. The Swiss defeated Anastasia Pavlyuchenkova who comes back after long injury, 7-5 6-4.

Start of the season does not look any brighter than whole the previous year for Garbine Muguruza. Two times Grand Slam champion who received a wild card for the main draw lost to Belinda Bencic. That was very interesting match from the statistical point, while the spectators could see just two breakpoints thorought two sets, both created and won by Bencic, which gave her a 6-3 6-4 win to find a place in R16.
