LONDON, England - Agnieszka Radwanska has a big second round challenge against the in-form Casey Dellacqua, and Li Na also seeks entry into Wimbledon's third round.

Wednesday, Second Round

No.2 Court
[2] Li Na (CHN #2) vs. Yvonne Meusburger (AUT #38)
First meeting
Both Li Na and her second round foe, Yvonne Meusburger, came into Wimbledon looking to put recent history behind them. Li had lost her last match against Kristina Mladenovic in her Roland Garros opener, and Meusburger had lost seven of nine matches - including four straight openers during the clay court season. But each of them got back on the winning track at the All-England Club on Monday, Li beating Paula Kania in straight sets and Meusburger defeating Vania King in straight sets.

"I came here one week earlier," Li said after her first round win. "But it doesn't matter how you play in practice and how long you've been on tour; there are still nerves when you go on court. I got down today in the first set, but I made sure it didn't turn out like the French Open."

Meusburger is 0-9 against Top 10 opponents, with her lone Top 20 win coming over World No.15 Nathalie Dechy in a 2005 Fed Cup match.

Centre Court
[4] Agnieszka Radwanska (POL #4) vs. Casey Dellacqua (AUS #36)
Head-to-head: First meeting
Some may have thought Agnieszka Radwanska was ripe for an upset after falling in her Eastbourne opener last week. However, the same thing occurred in 2012 and 2013, but she still reached the Wimbledon final in 2012 and the semifinals in 2013. And sure enough, she was in fine form in a first round rout of Andreea Mitu that she finished off on Tuesday.

As for second round opponent Casey Dellacqua, the No.2 Australian had to fight off a match point in a three set, first round triumph over Anett Kontaveit after coming into this fortnight full of confidence. She matched her best WTA outing with a run to the semifinals two weeks in Birmingham, after which she rose to a career-high No.36. She is 1-12 against Top 10 opponents, having upended World No.9 Marion Bartoli at the French Open in 2008.

Stat to watch: Dellacqua was outside the Top 200 at No.209 as recently as September, but has climbed 173 spots since.
