Ellis (oblique) was activated from the 15-day DL on Monday. Between a couple stints on the DL this season, Ellis has worked on the short end of a platoon at second base with Kolten Wong (neck), seeing starts against left-handers. Manager Mike Matheny may be inclined to return the 37-year-old to a similar role, but Ellis has posted just a .495 OPS through 191 plate appearances and the skipper could give more of those starts to Pete Kozma.
