7 years agoLos Angeles Dodgers closer Kenley Jansen could miss this weekend's series against the Rockies in Colorado for precautionary reasons. Jansen showed symptoms of an irregular heartbeat less than a month ago during a trip to Colorado and the high altitude. The closer spent 10 days on the disabled list after experiencing atrial fibrillation in Denver and returned to a bad four-game stretch before rebounding to record two saves in the last three games against Arizona. Jansen's owners have to be happy about his recent performances, but be ready to potentially be without him this weekend. If he doesn't make the trip to Colorado, Kenta Maeda, Scott Alexander and even Ryan Madson could all be candidates for save chances.--Keith Hernandez - RotoBaller
