Serena Williams (USA #1) vs.  Li Na (CHN #2)
Head-to-head: Williams leads 10-1
On Saturday afternoon, Li Na is faced with one of the toughest tasks in tennis: defeating Serena Williams in Miami. For Williams, the tournament, situated just 70 miles down the coast from her Palm Beach home, has brought her more success than any other, with a record six titles coming from her past nine visits.
After struggling to find her best tennis in the first week, Williams has used the rounds to play herself into form and produced a dynamic performance last time out, firing down nine aces in a straight set win over fellow Florida resident Maria Sharapova.
And the American cannot afford any drop off in the final because, as she has admitted previously, in Li she faces one of the most complete players on tour. This year, Li has succeeded in marrying her undoubted talent with a greater consistency, taking a 21-2 win-loss record into the final. Her path there, though, has not been entirely smooth sailing, and she was forced to dig deep to see off first Caroline Wozniacki and then Dominika Cibulkova.
Like many of her fellow Top 10 members, Li has struggled against Williams in the past, winning just one of their 11 career encounters. The most recent of these came at last year's WTA Championships, when Williams overcame an injury scare and a flying Li start to prevail in three rollercoaster sets.
Williams: "I always feel like anyone that I play, you have to be ready to play. You have to be ready to play no matter if you're playing the person that's ranked 200 or whether you're playing the person that's ranked No.2. You have to show up and if you don't show up, then your biggest threat will be yourself."
Li: "It's a good challenge, I think. The last time I played her was in the WTA Championships, so three, four months already. Here we can really see how I've improved in these three, four months."
