Diamond had pretty good K/9 numbers early in his minor league career but they consistently dropped as he moved up through the system. Darnell's K/9 is on the rise as he matures. He appears to be turning into a different level of pitcher as he gains experience and develops his pitches. I watched him in his debut last night and, even though the blister ended his night early, he settled in pretty nicely after giving up a homer to his first AAA hitter (k'd 2 guys in the 2nd maybe?). Some guys survive on raw talent alone and some guys survive on guts. Logan might fall into that category. He's got good make-up it seems. I don't care what anybody says, I like a guy who goes 6+ basically EVERY time he takes the mound. It means he's a strong competitor who doesn't necessarily have to have his best stuff to get guys out.
