Sorry, but I'm not trading him just to target a relief lefty, unless it's a proven commodity.
Hudson is 27 and threw 9 MLB innings prior to last year. Maybe he's a breakout, but I think it's just as likely, if not more likely, that he's a flash in the pan. Looks like his fastball only goes 90-91 MPH and he was also DFA'd by the Dodgers this time last year. The Dodgers aren't perfect, but they're pretty close; if they didn't believe in him, I'm not sure I'd want to.
Saucido threw only 38 innings in 53 games last year. I didn't know that kind of ratio was still possible in today's game. He's a total LOOGY and I don't want LOOGYs anymore; you have to be able to get batters from both sides of the plate out in today's game.
