Chad Orvella: More Questions Than Answers

Usually I like to give a firm opinion in these player profiles, but in this case I don't have one yet. I posted the following on rotojunkie this morning to see if anyone over there can help me out...I'd love to hear your opinions as well:

Can someone explain Chad Orvella to me?

How does someone whose minor league stats are IP:149.2, K:215, BB:26
Do this in the majors last year: IP:24.1, K:17, BB:20

Usually I would assume that there's an injury...but that doesn't make sense here. I haven't seen his minor league game logs, but it looks like he dominated in the minors, got called up and sucked in the majors, was sent down and dominated in the minors again, and then got called up and sucked again in the majors.

I don't really believe in 'quadruple A' players who dominate in the majors but don't have the stuff for the majors.

Is he one of those guys who just fall apart when the spotlight is on them...sort of a variation on Ankiel? Or is there some other possible explanation?

On another note...there's something else I'd like to ask for some help on. In an effort to get the word out about this blog I've been swapping links with other useful fantasy baseball sites - basically if their advice seems good and they update the site often I'm happy to let people know about them. If any of you have any suggestions of sites not already in my link list, let me know.
