Hernandez joined up with his colleagues on tour on Monday and he accompanied Sir Alex and Rooney at a United press conference at Manhattan's 'MLS Hub'. The All-Stars held their own conference, attended by David Beckham and Henry, at the same venue.
Ryan Giggs, Nemanja Vidic and Phil Jones were among a group of United players and officials who then went to Gracie Mansion, the residence of New York City Mayor Michael Bloomberg, for a photo opportunity and a signed shirt presentation.
And in the evening, club partners Hublot hosted a glittering event at the Cipriani on Wall Street, which included a gala dinner, a fashion show featuring some of United's players and a charity auction raising thousands of pounds for the MU Foundation.
