Acquired from the Detroit Tigers in exchange for backup catcher Vance Wilson, Hernandez hit .326 in 66 games at Double-A Binghamton and .303 in 66 games at Triple-A, earning the organization's Sterling Award as the top player at Double-A.
"It was a good year," Hernandez told reporters. "This was my best year."
Still, Randolph was inclined to stick with Matsui, at least until the infielder came up with a hamstring pull on Friday night.
A corresponding 40-man roster move – the designation of pitcher Dae-Sung Koo – was made to activate Hernandez, who was already in New York to get his elbow checked out and to accept his Sterling Award on Sunday.
