It could be a bumpy first season for 49-year old rookie manager Walt Weiss. He is taking over a Rockies’ squad that was only 64-98 (39.5%) in 2012. Weiss was a special assistant to Rockies’ GM Dan O’Dowd from 2002-08. He has been a high school manager since then. The Rockies have a pretty awful starting rotation and it’s hard to win when that is one of your biggest weaknesses. Weiss is going to definitely get a baptism by fire with the Rockies in 2013.
