Hernandez gave up one hit and struck out three over three scoreless innings in Saturday's Grapefruit League game against the Cardinals.
He entered the game in the fourth inning after Trevor Rogers got the start, and Hernandez promptly fanned Nolan Arenado to begin his day. The 26-year-old right-hander has yet to allow a run so far this spring and has a 6:0 K:BB through five innings as he looks to establish himself as a reliable arm at the back of the Marlins' talent-laden rotation.
