ALL NL Central leftys that you need to get out in critical situations. A lefty specialist also has little room or margin for error. A bloated ERA will happen because of said margin for error. But if a guy has the stuff that will baffle a lefty hitter (because he hides the ball well), he's going to win his fair share of battles. Also take into account that Miller is a proven veteran while McLemore and Randolph are both learning the craft of being lefty "relievers" in the bullpen. Neither McLemore nor Randolph throw side arm nor hide the ball particularily well to a hitter, they come over the top pretty much. Not to say they won't be good relievers, far from it. But if you had a critical situation in the seventh inning, you have two outs and Junior Griffey at the plate, you'd trust a guy like Miller to get him out, regardless of his bloated ERA. Randolph or McLemore may get him out, but a lefty who comes over the top and throws a straight as an arrow fastball (as Randolph does) is one that won't fool a lefty hitter at all. Those types of lefty's depend on making thier pitch to location. Remember Wilfredo Rodriquez and his straight as an arrow fastball to Barry Bonds? Miller will get more swing and a miss types of Ks to leftys because he hides the ball well and his slider just keeps darting away. He throws inside with his fastball enough to setup that nasty pitch to a lefty. Pedro Borbon used to do that a lot and he made very strong hitters like Brian Giles look foolish trying to hit his slider. So nothing against Randolph nor McLemore, both fine lefty relievers, but neither is a real candidate for lefty "specialist". So the question is really whether you need a specialist like that. The answer, of course, is look at the list above.
