The Rockies have selected right-hander TJ Shook for their MLB roster, replacing Zach Agnos, who was optioned to Triple-A. Lefty Welinton Herrera has been moved to the 60-day injured list due to a torn UCL, ending his season. Shook, who recently turned 28 and has performed well in Triple-A with a 2.86 ERA, was acquired last winter in the Rule 5 draft. Herrera, a promising prospect, faces uncertainty as the Rockies navigate roster decisions while rebuilding.
