How does the Miami Marlins pen look after their most recent trades?

The Marlins bullpen has been reeling this past month and it was in need of help.  In comes Kim Ng with two trades that may change the face of the Marlins late inning pen use.  Are they done or do they still need more?  I don’t think anyone would mind one more piece for the pen, and it could really solve all the Marlins recent struggles.  

The Marlins Friday night win against the Tigers highlighted the need for a new and improved pen.  The Marlins threw out four different relief pitchers after Braxton Garrett’s 6 inning gem and each successive pitcher gave up one run.  In the seventh through ninth innings only A.J. Puk finished a full three outs.  So now who is on tap with the new Marlins trade pieces David Robertson and Jorge Lopez along with the existing players in the pen?   

David Robertson will definitely close out games as he is consistent, with 14 saves in 17 chances. Robertson’s 2.05 ERA makes him the best reliever in the bullpen and the leader in the pen.  When Andrew Nardi returns he will likely be the setup man with Tanner Scott and A.J. Puk depending on the batters coming up.   The order could easily be Puk or Nardi in the 7th, Scott in the 8th and Robertson to close it out.  

Lopez could also work his way into the 7th inning rotation but likely will be more of a utility relief pitcher until he regains his All-Star form.  If Lopez could get back to his old self, the powerful righty could work as well in situations with more left handed batters up in the order.  Lopez’ splits look much better against lefties who are hitting .178 against as compared to righties at .296. Scott has pitched well against both lefties and righties.  

The Marlins still are in need of another arm that will consistently stop righties late in the game and if the roster is unchanged it would have to be Nardi, Scott, Robertson, even though right handed batters are hitting .256 against Nardi.  Adding an arm like Keynan Middleton would bring another balanced arm, with lefties hitting .207 and righties .243.  I hope they will but it will cost a lot to acquire another relief pitcher and they might not have the capital left to do so, and will have to live with Nardi, Scott, Robertson.
