As much as i don't like Tavarez, he does a decent job at saving the other pitchers arms during a blowout. With the loss of Snyder he is really the only one who can come in a give 3 or 4 innings. I think that he is important to have around since our some of our rotation (lester, Dice-K, and Wakefield) have shown that they can be wild and chased from the game early. Tavarez may not be great, but he is an important piece of the pen.
