MELBOURNE (Reuters) - Barbora Strycova expects to do a lot of running against Serena Williams in their Australian Open fourth round tie at Rod Laver Arena on Monday but the diminutive Czech will be no pushover for the world number two.

"She's a powerful player, and I'm so small," said 16th seed Strycova, who stands just over 5 feet 4 inches (1.64m).
