Justin Duchscherer has been diagnosed with clinical depression and will miss the remainder of the 2009 season.Duchscherer didn't throw pitch in the majors this year. He was lined up to make his 2009 debut last Tuesday, but was mysteriously scratched because of a non-baseball issue. We now know exactly what that issue was. "Justin has been battling this for quite some time, and it's kind of reached the apex where he made a really tough decision and owned up to the problem,'' agent Damon Lapa said Friday. "He wants to take a step back and really focus on addressing his personal issues off the field."
