In a season that's gone exceedingly well for the Los Angeles Dodgers, a late problem that popped up is causing a lot of concern: Can they still count on Kenley Jansen as their closer? "I'm very sensitive to what he has accomplished on the baseball field, as a closer and as a perennial All-Star, but we also have to look in real time, and do what's best for the Dodgers," said Roberts, though the manager hasn't been ready to make a definitive declaration about Jansen's role. Jansen's velocity has been noticeably down, and inconsistent, for much of the past month.
