So it St Louis

From the humble status of wild-card entry at St Louis last year, the US Grandmaster, Wesley So (formerly of the Philippines) has rocketed to first prize laureate this year and also overall leader in the Chess Grand Tour standings. Final scores in St Louis were: So 5½; Anand, Aronian, Caruana and Topalov 5; Vachier-Lagrave and Nakamura 4½; Ding Liren 4; Svidler 3½; Giri 3.
  The overall standings in the Grand Chess Tour are:  

Player	Points	Prize
Wesley So	30	$120,000
Magnus Carlsen	23	$67,500
Lev Aronian	21.75	$66,250
Hikaru Nakamura	21.5	$62,500
Fabiano Caruana	16.75	$58,750
Viswanathan Anand	14.75	$51,250
Veselin Topalov	10.75	$51,250
Maxime Vachier-Lagrave	17.5	$40,000
Anish Giri	8.5	$30,000
Vladimir Kramnik	8.5	$15,000
Ding Liren	3	$15,000
Peter Svidler	2	$15,000
Laurent Fressinet	1	$7,500

 

To be fair, world champion Magnus Carlsen was absent from St Louis, preparing for his world title defence against Sergei Karjakin. Given that fact, Carlsen’s second-place slot after the Paris, Leuven and St Louis legs of the Grand Tour is remarkable.
