CINCINNATI -- Former major league outfielder/first baseman Darin Ruf is suing the Reds for damages after he suffered a career-ending injury while crashing into an uncovered tarp roller at Great American Ball Park two years ago. In the third inning, Ruf was chasing a foul pop when his knee hit the end of the tarp roller. According to the complaint, Ruf suffered "permanent and substantial deformities to his knee." Ruf's complaint says the end of the tarp roller was made of sharp metal and had no protective cushioning or cap. Leaving an unpadded metal roller on the edge of the field is inexcusable."
