US President Joe Biden won most of the primary elections in the "Super Tuesday" states, but suffered a surprise blow in his march to the Democratic Party nomination after losing to little-known challenger Jason Palmer.

Australia's Jason Day, who followed up his maiden major triumph at the PGA Championship with a victory at the Barclays last week, paced a group of five on 68 that also included Gary Woodland, Ryan Palmer, Sean O'Hair and Daniel Berger.
