Wesley So retained the sole lead at the Sinquefield Cup after round five, but four players are now just half a point behind him. Fabiano Caruana recovered from his round-three loss to So by defeating Levon Aronian, while Vincent Keymer beat Anish Giri to join Caruana, Maxime Vachier-Lagrave and Praggnanandhaa Rameshbabu on 3/5.
