Plucked from a Japanese baseball all-star team roster in 2007 and introduced at a lavish news conference, Igawa was expected to be a staple in the Yankees’ starting rotation. He lasted 16 games, most of them regrettable outings that were sometimes spectacularly inept. Booed off the field, he was called one of the worst free-agent signings in Yankees history. After his last, losing appearance for the Yankees in early 2008, he was banished to the farm system and he has not come back.
