You may be right but an interesting comp is provided by Jalen Beeks and Tacoma righthander Rob Whalen, a pair of former 12th-round draft picks.
Beeks has been impressive in his cherry-picked 82.2 innings at Triple A this year. As notin noted, Beeks has not pitched in the hitter-friendly Pacific Coast League where Seattle's Triple A Tacoma Rainiers play.
In the larger and more meaningful samples of their minor league careers, Beeks and Whalen have posted these numbers:
JB 511 IP, 3.66 ERA, 1.26 WHIP, 158 BB, 484 K
RW 490 IP, 3.27 ERA, 1.22 WHIP, 165 BB, 431 K
And their minuscule MLB lines this year:
JB 6.1 IP, 12.49 ERA, 2.37 WHIP, 4 BB, 5 K
RW 4.0 IP, 0.00 ERA, 0.50 WHIP, 1 BB, 0 K
Whalen's four scoreless innings came in the Mariners' 7-6 win against the high-flying Red Sox:

Whalen's career MLB line:
RW 36 IP, 5.75 ERA, 1.19 WHIP, 15 BB, 27 K
Whalen is six months younger than Beeks.
I'm not suggesting that one pitcher is better than the other, but they provide interesting comps.
