After blowing another save last night, the Cardinals appear to be removing Edward Mujica from the closer role going forward.
Per Jennifer Langosch, the Cards will not use Mujica tonight and the closer spot will be "fluid going forward". There are various candidates to fill the closer role (e.g. Trevor Rosenthal, Kevin Siegrist) and game situations may determine who gets the call.
This news comes on the heels of Mujica's admission that he is experiencing "overall fatigue".
After being lights out for the first 5 months of the season, its obvious that something was wrong with Mujica as he has posted a 9.45 ERA in September and blown 2 out of 4 save chances. In 6.2 innings over 8 appearances, he has given up 15 hits, 2 walks and 2 homers.
The Cardinals will likely try to give him a breather for a few days and then put him in some low pressure situations to see how he responds. At this point, its about getting him back on track in time for the playoffs.
Although the Cardinals say that they will determine the closer based on game situation, Rosenthal is the logical choice to replace Mujica. This final week may be Rosenthal's audition for the 2014 closer role (and beyond).
I think he will do just fine.
