EDGE Analysis
Kopech, who fanned 10 over 5.2 innings for Double-A Birmingham on Wednesday, finished the month 3-1 with a 2.31 ERA and 47 strikeouts over 35 innings. The 21-year-old right-hander with the legendary fastball initially struggled with control, throwing strikes on just 57 percent of his pitches with an 8.2 BB/9 through the first three starts, but has improved to 64 percent and 4.7 over his most recent seven starts. That has led to him getting deeper into games and developing on a quicker schedule.
