In this month’s closer look, let’s discuss the value of middle relievers.  I’m a big Mr. B.  Depending on the team, I have various combinations of MRs.  On one team, I have C.J. Wilson still.  (Notched a Save and a Win in a doubleheader the other day — natch!)  On another team, I’m rocking Dan Meyer.  On another, Rafael Soriano.  Besides having a guy that could take over the closing duties, middle relievers help lower your starters’ ratios.  Mark DiFelice + James Shields = 7-4/3.01/1.15/74 or Jake Peavy, 5-5/3.67/1.13/84.  That’s right, the Frankenpitcher of Jark DiShields is beating the pure breed Jake Peavy.  So how’s dem apples?  Delicious!  Now in some cases, you just can’t hold a MR.  Whether you’re besieged by injuries, need to handcuff one of your closers or need a bench hitter, sometimes it’s just not feasible.  As much as I like MRs, they are invariably the first ones I drop on my teams when I need help somewhere else.  Luckily, there’s always one available on waivers.  If it’s not Jark DiShields, you can own Kiko Garzero or C.J.
