PHOENIX — Gorkys Hernandez didn't know until he got to the ballpark that he'd be in the lineup.

With Denard Span out due to tightness in his hip, Hernandez took over in center field and the leadoff spot, driving in four runs to lead the San Francisco Giants past the Arizona Diamondbacks 8-4 on Tuesday night.
