Gorkys Hernandez drove in four runs and the San Francisco Giants bounced back from blowing a save in their season-opening loss to beat the Arizona Diamondbacks 8-4 on Tuesday night. Johnny Cueto (1-0) went five innings for the win, despite giving up home runs to Jake Lamb and Paul Goldschmidt. After new closer Mark Melancon blew a save in Sunday's 6-5 defeat, four Giants relievers combined to allow one hit over four scoreless innings this time.
