I like. Is it that much less nasty with Piggy or Lahey instead of Marte? Or with Leiber in long relief and Hart in short relief? Especially when whoever gets the final pen spot will be basically the 25th man on the roster? Is it that much less nasty to pay more in money and prospects to upgrade it? That's the same point people make for not making the Roberts' trade. Getting Marte makes a good bullpen better. Of course, everything depends on cost. It's completely different. You are talking about getting better for 1 inning at a time, 70 games a year. With Roberts you are getting a 9-inning/ 150 game per year player. It's completely the same. You take a good situation and upgrade it to make it better. That 1 inning at a time, 70 games a year possibly could make a swing of 8-10 wins depending on the situation. I could argue the VORP of Roberts over DeRosa is less than the VORP of Marte over Pignatello or Cotts. I repeat, you make a good situation better in either case. Except in the bullpen situation, managers choose specifically what innings can go to which pitchers. Marmol, Howry, Wood, Wuertz, and Eyre can take all the significant innings. The other 2 bullpen spots just need to eat innings where the Cubs are up by more than 4 runs, the Cubs are down by more than 2, or the starter has gone out early. In essence, if you acquire Marte all that you are doing is wasting Wuertz by pushing him into throwing those insignificant innings. Is it really at all important to acquire another pitcher just to throw in those situations where the game is basically over anyway? Do you really want Eyrehead as the lone lefty in the bullpen?
