The bullpen was already considered rebuilt even before Kenley Jansen went down with foot surgery that will cost him April and possibly May. Mattingly said management stockpiled as many arms as it could for insurance.
Mattingly said he was excited to get started, but said it's a little anticlimactic as most of the position players have been "unofficially" working out at Camelback Ranch in the week since pitchers and catchers reported.
However, Mattingly said this camp will have "a little more open competition" with "decisions to be made."
Center field is the most obvious spot up for grabs, but there will be significant focus on the bullpen.
