Larry Dierker Color commentators are often former players or managers. Good ones have a background in the game and can tell the listener or viewer what's going on in the minds of the players and explain the strategy. This year, Houston Astros fans are lucky. This year, the Astros welcomed back Larry Dierker to the broadcast booth. Dierker is a special kind of color commentator. He's a former player. He's a former manager. He's a newspaper columnist and an author. He knows the game well. He has a passion for it. Whenever he speaks, the viewer is educated. Even the lifelong fan learns something when Dierker works a game. Dierker's skills are such that he's even worked games on the networks (NBC and ABC when they had the Major League Baseball package), and in past years, the occasional game on Fox. Unfortunately, the Astros have yet to bring Dierker back full time. He's just a fill-in, working a schedule only Roger Clemens could love. So, Astros, finish the job and bring Larry Dierker back full time.
