You've probably heard by now that Paul Lo Duca, in his one-game color commentary stint on MASN, said that Ryan Zimmerman has a "little nerve issue" in his left shoulder, saying it's nothing serious and comparing it to the feeling you'd get if you slept on it wrong.

It wasn't a secret Zimmerman had hurt his left shoulder -- he slid headfirst into second last Sunday in Baltimore and had the shoulder wrapped up in the clubhouse this week -- but Lo Duca brought it up after the third baseman took an awkward swing in the eighth inning on Saturday night.

Anyway, manager Manny Acta wasn't concerned by the comments. "That’s his prerogative. I can’t tell Paul what to do," Acta said. "I had no idea what’s going on. I’m not listening to that game upstairs. I have no time for that."

Lo Duca bristled at the notion that the Nationals might be upset by his comments.

"Why? What'd I say on the air, because he slept on it wrong? Come on," he said, before ending an interview with reporters when it was suggested that the general rule is one player shouldn't talk about another player's injuries. "Don't make a mountain out of a molehill," he said as he walked off.

So there you have it. Different ways of handling the question, but from Acta and Lo Duca's comments, there doesn't seem to be much of a flap about what he said.

For his part, Zimmerman said he'd prefer if no one had found out about the injury, "because then I wouldn't have to answer all the questions," he said. "But it's all right."

He'll take his second day of the year off on Monday to rest the shoulder; Acta said he probably would have taken one anyway, with back-to-back day games.
