#4 – The bullpen will be improved from 2014
In 2014, the Tigers bullpen left much to be desired, especially from the closer position. Joe Nathan was an absolute train wreck for much of the season and though he was much better towards the end of the year, he will will have a short leash in 2015. I fully expect Nathan to last less than a month and Joakim Soria will take over the duties of closer and dominate.
Bruce Rondon starting the season on the DL is also a cause for concern, but assuming he comes back strong, he will be a huge addition for the Tigers in 2015.
Bold Prediction: The bullpen will convert roughly 75% of their save situations, good enough for top 10 in the league.
