The 27-year-old will lose his place on the active roster to Spencer Horwitz (concussion), who was activated from the injured list Sunday. Cook hasn't taken advantage of his chances in the big leagues this year and has a .200/.200/.267 slash line with 18 strikeouts in 45 plate appearances.

Cook was in the lineup for only the fourth time since returning to the majors on June 10, and he took advantage of the opportunity. He played a key role in the Pirates' early offensive production, recording an RBI or a run scored in three of the first six innings. While it was a nice showing, Cook isn't a viable fantasy option due to his lack of playing time.
