Leiter did have a good career prior to last year, but stubbornly held on and forced people to watch him throw 100 pitches in 5 inning starts. Leiter was on the USA team for the WBC and pitched 2/3 of an inning in the loss to Canada and gave up two runs. After that, even Buck Martine wouldn't think of putting him in a game.
Perhaps Leiter can start his rumored political career in New Jersey now. Or become one of baseball's new talking heads. He can be the yin to Tim McCarver's tempestuous yang.
