Frank Francisco will have an MRI on his right right latissimus dorsi muscle Saturday. Francisco left the game after walking Jeff Larish to lead off the ninth. He had a cortisone shot Monday. Francisco said he felt a pull on his right side and he didn't want to make it worse or overdo things.
Francisco said he felt the pull on the second pitch he threw to Larish.
"Every time I threw I felt like it was getting worse," Francisco said. "It's not worth it."
Francisco has pitched just three times in the last 15 games, pitching just 1 1/3 innings.
