( CNN ) -- Serena Williams is almost unstoppable in Miami . She showed that again Saturday . Playing close to her home in Florida , Williams started slowly before picking things up and beating Li Na 75 61 for a record seventh title at the Sony Open . She became just the fourth women 's player in the Open Era to claim the same tournament at least seven times , joining retired legends Martina Navratilova , Steffi Graf and Chris Evert . And no one had ever won seven Miami titles , too . `` It was a really important victory , especially playing Li Na , who has been playing so well , '' Williams told the crowd . `` She started out so well . `` I was like , 'Oh my gosh , I just need to hang in here . ' Then I heard some fans trying to pull me through . If it had n't been for you guys I would n't be standing here right now . '' In a battle of the two top-ranked players in the world , Australian Open champion Li -- she 's the No . 2 -- stormed out to a 5-2 lead and even held a set point on her own serve . But Williams recovered and won 11 of the next 12 games to capture her second title of 2014 . She 's now 11-1 against Li . `` I do n't think I was playing badly , '' Li was quoted as saying by the WTA tour 's website . `` She just started playing a little bit better after she was 5-2 down . `` I do n't think I had the wrong game plan today or played wrong . I think it was still a pretty good match . And I was trying so many things like coming to the net more , so it 's not bad , really . '' On Sunday , the top two in the men 's rankings will also play .
