Matt Holliday left Sunday's game against the Royals with a mystery ailment that has plagued him for a while. "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," Joe Strauss of the St. Louis Post-Dispatch tweeted. "[Mike] Matheny described Holliday condition as "leg"-related. That's a little broad. Again... Developing," he continued. Holliday was 2-for-3 with a homer when he was removed.
