Coming into the season, I had Ryne Nelson as the top pitching prospect and #5 overall with a solid shot of developing into a middle of the rotation arm. Nelson was coming off a season in which he produced a 3.51 ERA, which is downright elite in the crazy run scoring environments he had to pitch in with Amarillo, backed up with outstanding peripherals. Nelson punched out nearly a third of the batters he faced with Amarillo with a solid walk rate of just above 8%. While his corresponding FIP was 4.06, the high home run total can be explained away by the homer-happy environment in Amarillo with an elevation of 3600 feet, relatively dry climate, and winds that can turn the park into a band box.
