The Rockies reinstated Herget (shoulder) from the 15-day injured list Wednesday.
Herget will make his return to Colorado after missing over a month of action due to a shoulder impingement. Before being shelved with the injury, the 32-year-old recorded a 5.06 ERA, 1.38 WHIP and 17:4 K:BB through 16 innings this season. In order to make room for Herget on the active roster, the Rockies optioned Seth Halvorsen to Triple-A Albuquerque.
