ST. LOUIS—After being named hitting coach by Cardinals manager Tony La Russa, Mark McGwire told reporters Monday that he is eager to get back in the batting cage and work with the team's hitters on the fundamentals of avoiding direct questioning from Congress during committee hearings on steroid abuse. "When you get down to it, it's just hands back, quick to the ball, and then right when you are about to shift your weight, have a working knowledge of the Fifth Amendment so as not to incriminate yourself in front of a panel of elected officials," said McGwire, who in the past has informally helped Cardinals Skip Schumaker and Chris Duncan with swing tips, including one in which you choke up a quarter inch to make certain you cloud the truth. "I'm not going to impose my style of squirming and smoke-screening on their batting stances, though. Every individual player needs to figure out how best to keep his left shoulder behind the ball in order to eventually make his deflected answers that much more precise." When asked about his history with performance-enhancing drugs, McGwire patiently kept his hands back and delivered a short, powerful swing to the reporter's face.
