Padres manager Bud Black said Friday that Carlos Quentin (knee) could begin the season on the disabled list. Quentin is dealing with some soreness in his left knee, which is actually his "good" knee. The Padres open up the season Sunday night, so a decision on the outfielder's status will have to be made soon. Quentin has averaged just 84 games played in his two years with the Padres.
