Right now for the bullpen Penders has been relying heavily on the foursome of Radue, Rajkowski, Dandeneau, and Russell. These guys have been reliable for the most part. Penders has also given some time to Rossomando, trying to break him into this group as well. Jacob Wallace has gotten some time as well.
One thing that will help the bullpen is when the starting rotation settles out and starts to give a consistent 6 or so innings a start, and leave the bullpen less taxed. Domnarski's quick demise as a weekend starter and Tim Cate's injury have added to the bullpen load. Mason Feole has been giving a solid set of innings as the Sunday starter in place of Domnarski. Next, the return of Tim Cate is needed, not only in terms of quality but in the quantity of innings pitched. Poulin and Nepiarsky each went about 3 innings when they started for Cate, not to mention the shortened start when Cate had to leave the Texas game early.
