Yes, you need to take your opportunities if you are feeling fresh and opponents are not.
She will play Urszula. H2H is 1-1. Mandy won the most recent one at the French in 2011, 2 and 5. On the other hand Mandy lost 1 and 2 to 15-yr old Urszula back in 2006. So I guess Mandy improved more in the following 5 years than Ula
Not sure which way this one goes- Urszula is in good form right now apparently.
