Mildy concerning? Dude is striking out 4 per 9. To put that into context, Gibson and Buerhle are striking that many out in the majors and that's almost unacceptable. Well, it makes them backend starters in the long run even if they do get decent results at the moment. If you adjust that strikeout ratio to the majors, you probably get a Blaine Boyer and that's being generous. He's going to fall out of a lot of top 100 lists if this continues. He got a free pass last year because he was just getting used to professional baseball but if he doesn't get swings and misses in the low minors, hes doomed.
