This seems like a rather bizarre move. Kennedy was lights-out in his one minor league start, and Igawa was spanked in his MLB start, but this seems like a drastic move based on one game.
Especially after his comments to the press, if he gets lit up against the Mets (very possible) it could turn into a trainwreck. They're really throwing him into the fire here.
Igawa has had a decent AAA performance thus far. Should they have given him more of a chance, especially with the millions upon millions of dollars invested in him?
