"I just have to be ready at any time," Hudson said. "[Robin] Ventura is the manager. So, whenever he calls on me, I have to be ready."
Hudson, 34, could spell Gordon Beckham at second base for a game against a tough right-hander. The veteran of 11 seasons also will factor in as a pinch-runner and defensive replacement.
"I didn't think this early in my career I would be at this road, so it's a little shocking," Hudson said. "But it's a part of the game. All I have to do is stay ready."
