The guy who has impressed me of late is Alcala. For one thing, you can count on him for two innings (not sure I would say the same about most of our bullpen), and there are times where that is at least desirable and maybe necessary. He's also young and on the upswing, sort of like Dobnak was last year. With the caveat that they all have done well this year and all are excellent component parts, I would probably drop Stashak and Wisler. Stashak is mostly injury concerns - if there are none, then I'd keep him and drop Clippard. With Wisler, I just don't trust a one pitch pony. Granted, you might say the same about Romo, but Romo has proven it in high leverage situations for a longer period of time. Clippard has done fine, but he is at the bottom of this strikeout list.
