No big diary here, just a heads up. Mike Fast at MVN.com wrote a brilliant 3-part article on how Brian Bannister succeeded and what that means for the future. I'm linking to part 3 because I think it was the best one, but it contains links to parts 1 and 2 as well.
One of the reasons I liked part 3 so much is that it provides some support for my contention that Bannister has a low BABIP in part because of his pitch selection skills. He knows what pitches to throw, when to throw and who to throw them to.
His basic conclusion is that Bannister's low BABIP was a combination of skill and luck and that we should see some regression, but not the kind of falling-off-the-cliff that some projection systems and analysts are predicting.
Warning: these articles are full of technical sabermetric content. But I think they are fairly easily understandable.
