Tennis-Sharapova hoping for clearer skies on Tuesday

By Michael Hann LONDON, June 30 (Reuters) - Maria Sharapova, bidding for a second Wimbledon title 10 years after her first, is hoping her delayed fourth round tie against ninth seed Angelique Kerber will finally go ahead on Tuesday. With rain disrupting the schedule on Monday, fifth seed Sharapova's match against Kerber succumbed to the weather so she is due to open Centre Court action on Tuesday instead. Kerber said she would not be thinking about who was on the other side of the net. "I have nothing to lose," said German Kerber. "I will go out there, try and enjoy the match and focus on myself. "I will not focus on her or against who I am playing." World number one Rafael Nadal follows Sharapova on the main showcourt, where he will play 19-year-old Australian Nick Kyrgios who is the first wild card to reach the last 16 at Wimbledon since Juan Carlos Ferrero in 2009. "Young players are very dangerous," said Nadal who has lost the first set in his opening three matches. "They are able to play with no pressure. "He has a great serve and is an aggressive player." An all-Czech affair rounds off matches on Centre Court when sixth-seed and 2011 champion Petra Kvitova takes on surprise package Barbora Zahlavova Strycova in the quarter-finals. A third Czech, Lucie Safarova, will play 22nd-seed Ekaterina Makarova in the day's other quarter-final on Court One after Roger Federer, looking for an eighth Wimbledon title, meets the experienced Spaniard Tommy Robredo. Third seed Simona Halep, the highest ranked woman left in the tournament, plays Kazakhstan's Zarina Diyas in the fourth round and they will be followed on Court Two by Australian Open champion Stanislas Wawrinka and Spain's Feliciano Lopez.
