On paper, Jason Arnold had a very good minor league career.
The second round draft pick began with a 7-2 mark and a 1.66 ERA, while averaging more than 10 strikeouts per 9 frames, in his first campaign (2001); he was 13-4, 2.61 with a 8.9 K/9 IP ratio his sophomore year. His record fell to 7-9 in 2003, though his ERA was a solid 3.69, with a similar tale the next year: 2-5, but with a 3.61 mark.
Two-thousand-and-five illustrated his downfall: In his first, and only, full season at Triple A, he was 0-4 with a 6.39 ERA in 47 relief appearances. He averaged less than a hit allowed per inning and posted a solid K/9, but too many balls left the yard — he surrendered 14 dingers in 62 innings (that’d be 45 in a 200-inning campaign).
Abbreviated though it was, just 12 games, 2006 was a rebound season, as Arnold posted a 1.90 mark with a 11.0 K/9 in 23.2 innings. It wasn’t enough to save his career, however, and he was out of the game after that. His record and ERA outside of Triple A: 24-11, 2.29. In Triple A: 5-15, 4.79. He never made the majors.
