Boy, he sure is making a case for himself, isn't he?
Yeah, yeah, he was facing a AAA lineup. His fielding independent ERA is 1.30 runs over his actual ERA. Dude's getting it done, and sometimes you just gotta look at the bottom line.
The only thing about Lannan that I can't get over is the strikeout rate (or lack thereof). He's striking out only 9.9% of batters faced, or 3.74 Ks per 9 innings. The only pitcher in baseball with 70 IP or more with a lower rate this year is Shairon Martis, who is getting hammered at AAA right now.
Jamie Moyer has had sustained success with K-rates that low, and maybe Lannan really is the next Moyer. He certainly has the maturity and patience for the "wear you down with 85-mph pitches on the black" approach.
And if he is the next Moyer, rejoice. A really good, extreme-command soft-tossing lefty can do this for years and years and years and years.
