Overview

  • The Rockies optioned rookie Chase Dollander to Triple-A Albuquerque and recalled Bradley Blalock to fill his rotation spot.
  • Over 15 starts, Dollander posted a 2–9 record with a 6.68 ERA and failed to pitch beyond the fourth inning in his two July appearances.
  • He missed nearly two weeks on the injured list with right forearm tightness before returning to the mound on June 3.
  • Despite averaging a 97.7 mph fastball, he ranks in the 26th percentile for whiff rate and the 3rd percentile for barrels allowed, magnified by Coors Field’s hitter-friendly conditions.
  • Colorado still regards the 2023 ninth-overall pick as a future anchor of the rotation and will monitor his development in Triple-A.
