I think Laura often has an advantage for the first few games due to her unusual left-handed sliced serve being unfamiliar to the opponent. Once they have adjusted then the games get tighter.
Naomi will need to find her game to beat Perry, others have a great chance (depending on how the qualifiers are drawn).
Naomi's draw is a hard one to gauge. Shenay has plenty of pedigree on grass but a poor year so far with no main draw wins, so will be short on confidence.
