Good news for Serena Williams that seems to have recovered after struggling in Wimbledon for a mysterious bug (see article).
Serena dismissed world no. 45 Karolina Pliskova 7-5 6-2 in just 64 minutes. The American was a bit rusty especially in the first set to grab the match after committing 19 unforced errors.
In the next round the world no.1 will face either Zhao or Ana Ivanovic.
