PHOENIX - A month after losing him to what they hoped was a minor ankle injury, the Nationals finally figured out what exactly was wrong with Adam Eaton. That's the good news. The bad news: It required surgery to figure it out.
Eaton had arthroscopic surgery today in Green Bay, Wis., to remove a flap of cartilage that didn't show up in any of the three imaging tests the Nationals gave the outfielder over the last month but was the source of his pain any time he tried to run.
