While I like Lannan and see no reason to toss him on the scrap heap for an unknown quantity, it would behoove you to spell Lannan's name right. It looks silly.
I don't think we will ever see dominance from Lannan, but he does seem much more confident on the mound lately and I also believe it has to have something to do with the much improved defense. Lannan is the type pitcher that seems to fall apart when the opposing lineup gets a 4th out due to an error.
I would have no problem with Lannan as the 4th or 5th starter, and he has pitched well lately. I would also like to know where the added velocity came from. It isn't really weird though for a starting pitcher that looked slightly below average to suddenly come into their own in their late 20's.
