3 of those names are starters so you did not even understand what i am saying
What you're saying is stupid.
All you have to do is look at this bullpen to know why it's struggling. It's filled with pitchers who are pitching like crap.
Blake Treinen has been notorious for control issues since he got to the Nats system. That he's struggling now shouldn't be a surprise. The guy who was a 4+ BB/9 the last two seasons is now forced in to a role where he must throw strikes. He's getting hit. And still walking guys.
Enny Romero has always been a lefty version of H-Rod. That's why we got him for nothing.
Solis is still inexperienced.
Oliver Perez is what he is and we've known it.
So that leaves Koda Glover, Shawn Kelley, and Joe Blanton. Glover is young and inexperienced. Kelley has always been somewhat long ball prone. And Blanton ... he's 36 and was available for a reason. Free agent relievers are usually a gamble.
Stop looking for some sort of metric centric reason as to the why the pen sucks. It's simple: It's filled with inexperience and declining skill.
