Pfaadt was promoted from Double-A Amarillo to Triple-A Reno on Tuesday.

EDGE Analysis

One of Arizona's best pitching prospects, Pfaadt had a 4.99 ERA, 1.27 WHIP and 82:9 K:BB in 57.2 innings over his last 10 starts while pitching in hitter-friendly conditions. The conditions won't get any better in the Pacific Coast League. Pfaadt's 3.65 xFIP at Double-A is a more indicative mark as to how well he did at that level. He could join the big-league rotation early next year.
