Matt Holliday's exit from Sunday's game against the Royals was curious, given that it was hard to tell when he might have been hurt. But whatever it was that took him out, it's not a new ailment, according to Joe Strauss of the St. Louis Post-Dispatch:

Holliday left 9th inning with a persistent condition that has worsened or at least flared anew. It's not his back. Has roots to a month ago.

Matheny described Holliday condition as "leg"-related. That's a little broad. Again... Developing.
