"I'm kind of frustrated about that, but I've got to stay positive in the head and hope to overcome this little bump in the road," Dyson said. "It's just frustrating, because it seems like every time I get a chance to play every day or whatever, something happens. Like in Baltimore, I was going good and messed my ankle up on one swing and it took me out for a couple days."
Dyson had hoped to be using the remainder of this season to prove himself to the Royals for next season. Instead he'll be spending his time likely limited to pinch-running duty for the rest of 2012. Dyson has been hampered by a strained lat muscle under his right shoulder that occurred during a collision with the wall in Boston on Aug. 27.
The outfielder had enjoyed an eight-game hitting streak before the injury, and has played in just two games since then, pinch-running in both appearances.
Dyson has said he can swing the bat yet is unable to throw, despite his shoulder pain improving each day. He was hitting .270 on the season with no home runs and nine RBIs.
