I think so 280 points is her 16th best result but she won titles at both Marbella and Luxembourg so I dunno if they are both included in that If they're both not included Vika would lose 280 points from Marbella but then the 280 from Luxembourg would be added
If they are both included and Vika loses almost another 300 points the difference between her and Maria could be around 400 and a title at Stuttgart would have Maria as number one Even if she doesn't win there she will probably get it at Madrid where Vika has 700 final points to defend - If Vika lost early, Maria could only need a win or two at Madrid to overtake her
And there's a good chance to finish the year at number one. Vika needs to win at least Wimbly or US/Open. Petra I'd say too many points to defend. Can't see Aga winning a slam. So yes there's a good chance. As longs as Masha doesn't get a long term injury.
