LaRoche received a cortisone shot recently and is expected to be the designated hitter against the Braves on Monday. He will play first base against the Mets on Tuesday.
"There is a little bit of fraying on the labrum and from what I've been told, that is nothing unusual," LaRoche said on Sunday. "They don't have to [operate] on it, obviously. It's just some more rehab and strengthening the muscles. ... I'll take [Sunday] off and play [Monday]."
LaRoche has had shoulder problems ever since he arrived in camp. The pain grew worse and it forced him to miss the first few games of the exhibition season.
