Pirates shortstop Bobby Crosby lauded the teaching skills of Mark McGwire after driving in four runs on Sunday. Crosby has worked with McGwire over the last three winters. "He's a good guy to have around," Crosby said of the Cardinals' new hitting coach. "He worked with me on being direct to the ball, taking a straight path. There's a lot more that goes into it, but he's a guy who really knows a swing."
