Colorado Rockies call up TJ Shook, option Zach Agnos to Triple-A

The Colorado Rockies have made three changes to their pitching staff ahead of their upcoming games. Right-handed pitcher TJ Shook was called up from Triple-A Albuquerque, making his MLB debut. Zach Agnos was optioned back to Triple-A after struggling recently, while Welinton Herrera was transferred to the 60-day injured list due to elbow inflammation. Shook is currently leading the Pacific Coast League in saves this season. Agnos had previously shown promise but faced difficulties in his last two outings, allowing 14 earned runs over three innings. Herrera had recently joined the bullpen, contributing effectively before his injury.
