Kopech allowed four runs on three hits and one walk while striking out two over one inning in Tuesday's game against the Mariners.

EDGE Analysis

Kopech is facing major-league hitters for the first time this spring, so it's understandable that the results were not good Tuesday. The right-hander with the legendary fastball lamented poor execution, particularly when he fell behind hitters. The 20-year-old Kopech, who is Chicago's third-ranked prospect according to RotoWire, is expected to open the season at High-A Winston-Salem or Double-A Birmingham.
