Urrutia is taking anti-inflammatory drugs and resting. He was scratched from today's trip to Fort Myers.
Urrutia said the shoulder began to bother him during Friday's exhibition opener in Port Charlotte after he made a throw to third base.
"I feel better," he said through his interpreter, first baseman Chris Marrero, who is sidelined with a strained oblique.
"I think it was just something where I didn't stretch it or warm my arm up."
Urrutia said he's never experienced shoulder pain in the past. It doesn't flare up when he swings a bat.
Marrero felt more discomfort on his side while throwing yesterday. He will attempt to work out next week.
