Royals' Alec Marsh: Out with undisclosed injury

Marsh has not pitched since June 15 due to an undisclosed injury.

This has been a particularly tough minor-league injury designation to track down. He logged a 4.97 ERA in six starts at Double-A prior to suffering the injury, but his 39.6 percent strikeout rate and .217 batting average against were strong marks. It was his 12.3 percent walk rate that was the big problem for the 23-year-old righty.
