Cardinals' Cooper Hjerpe: Too many walks at High-A
Hjerpe has a 7.50 ERA, 1.67 WHIP and 16:9 K:BB through his first three professional starts with High-A Peoria.
The Cardinals' first-round pick in last year's draft, Hjerpe has missed plenty of bats in the early going, but his 15.5 percent walk rate is the primary reason he has struggled. Hjerpe, who was born in California, is also pitching in the Midwest League, which can have a challenging climate in April.
