Dirt og is an athletic nickname given to certain baseball players who are considered "scrappy" or blue-collar, hardworking and tenacious and generally rough around the edges. This title first started in the Boston Red Sox organization in July 2001. The original dirt dogs are widely considered to be Trot Nixon and Brian Daubach. Both players gained great popularity in Boston for this particular style of play. This tag later was stuck to players such as Lou Merloni, Mike Lansing, Chris Stynes, Bill Mueller, Kevin Youkilis, Kevin Millar and current captain Jason Varitek. Trot Nixon is still widely accepted as the ultimate dirt dog, for his play, his dirty cap and his pine tar caked helmet.
