Karolina Pliskova beats Victoria Azarenka in Wimbledon second round
Karolina Pliskova won a Wimbledon battle between former world No 1s against Victoria Azarenka.
The Czech seventh seed triumphed 6-3, 6-3 in the Centre Court opener and kept alive her hopes of a maiden grand slam title.
Azarenka, who is ranked 87th in the world, is only just getting back to tour action after a custody dispute involving her son.

Azarenka powers the ball back towards Pliskova but she proved no match for the Czech star
She was competitive throughout the second-round clash, but Pliskova won out in the big moments.
Madison Keys celebrated Independence Day by moving into the third round.
The American, seeded 10th, made light work of Thailand's Luksika Kumkhum as she recorded a 6-4, 6-3 victory.
Keys was pleased to mark July 4 so positively but was struggling to find other ways to enjoy the day.
'I won so that's a good start, I'm happy,' she said. 'I don't know how I will celebrate - maybe have a barbecue or something.
'Obviously London doesn't really care about July 4. There's not much going on.'
British hope Katie Swan's Wimbledon run was emphatically ended by 29th seed Mihaela Buzarnescu.
Nineteen-year-old Swan won a main-draw match for the first time at the All England Club on Monday but found Romanian Buzarnescu, who has shot up the rankings over the past year, just too good.
Swan did not manage to win a game until the start of the second set and her hopes of a comeback were ended when Buzarnescu wrapped up a 6-0, 6-3 victory.
Croatian Donna Vekic followed up her toppling of fourth seed Sloane Stephens with a 7-5, 6-4 win over Rebecca Peterson.
Evgeniya Rodina will meet Keys next after a 6-1, 2-6, 6-3 success against Sorana Cirstea, while Yanina Wickmayer beat Andrea Petkovic 6-4, 6-3.
