Serena Williams losing here is tough to envision.

Na Li's result at the 2010 Australian Open will likely thrust her close to the top 10 on the women's tour however she is still coming in as a huge underdog against top ranked Serena Williams in one of the semifinal matches.

If you are looking to pound Serena, then Boylesports is your site as she is priced at -650 (2/13) there.  It feels like a safe bet to make although the short odds are not all that exciting. 

Williams' epic victory over Victoria Azarenka in the quarters isn't likely to be followed up by lackluster play and so there's no way you can pick Na Li for an upset here.

However, if you were interested in Li, use bet365 where her price is +500 (5/1) but our recommendation is to pound Williams hard.
